The software structure of any program running on the module can be broken down into the following components:  Radio stack  Bootloader (optional)  Application
NINA-B3 series - Data Sheet UBX-17052099 - R02 Functional description Page 10 of 50 1.7.1 u-blox connectivity software The NINA-B31 series modules are pre-flashed with u-blox connectivity software. The u-blox connectivity software enables use of the u-blox Low Energy Serial Port Service, controlled by AT commands over the UART interface. The NINA-B31 modules can be configured using the u-blox s-center evaluation software, which can be downloaded from the u-blox website and is available free of charge. Much more information on the features and capabilities of the u-blox connectivity software and how to use it can be found in the u-blox Short Range AT Commands Manual [2]. 1.7.2 Open CPU The open CPU architecture in the NINA-B30 series modules allows you to build your own applications. u-blox recommends the following development approaches to speed up the process: 1.7.2.1 Nordic SDK The Nordic Semiconductors nRF5 SDK provides a rich and well-tested software development environment for nRF52 based devices. It includes a broad selection of drivers, libraries, and example applications. It also includes other radio stacks. The NINA-B3 series modules are only certified for use with the S140 Bluetooth Low Energy SoftDevice. If you would like to use another 2.4 GHz radio protocol, contact u-blox support for your area as listed in the Contact section. 1.7.2.2 Wirepas connectivity software The NINA-B30 series modules can also be used together with the Wirepas software stack. This will enable the NINA-B30 module to be used in a large scale mesh environment. The Wirepas connectivity software is a third party licensed software from Wirepas. For more information about the Wirepas connectivity software, contact the u-blox support for your area as listed in the Contact section or contact Wirepas directly. 1.8 Bluetooth device address Figure 2: NINA-B3 software structure and available software options NINA-B3 Software structure Bootloader Radio Stack Application NINA-B31 series NINA-B30 series options Nordic S140 SoftDevice u-blox connectivity software Nordic SDK Wirepas mesh Connectivity Software + SDK
NINA-B3 series - Data Sheet UBX-17052099 - R02 Functional description Page 11 of 50 Each NINA-B31 module is pre-programmed with a unique 48-bit Bluetooth device address. For NINA-B30 series modules, or if the memory of a NINA-B31 module is corrupted or otherwise lost, the address can be recovered from the data matrix barcode printed on the module label.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 12 of 50 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) The NINA-B3 series uses integrated step-down converters to transform the supply voltage presented at the VCC pin into a stable system voltage. Because of this, the NINA-B3 modules are compatible for use in battery powered designs without the use of an additional voltage converter. You can choose one of the following two on-board voltage converter options:  A low-dropout (LDO) converter  A DC/DC buck converter Normally, the module will automatically switch between these options depending on the current consumption of the module. Under high loads such as when the radio is active, the DC/DC converter is more efficient, while the LDO converter is more efficient in the power saving modes. 2.1.2 Digital I/O interfaces reference voltage (VCC_IO) All modules in the u-blox NINA series provide an additional voltage supply input for setting the I/O voltage level. In NINA-B3 series modules, the I/O voltage level is similar to the supply voltage and VCC_IO is internally connected to the supply input. Therefore, only a single supply voltage is needed for NINA-B3, which makes it ideal for battery powered designs. ☞ This may not be the case for other modules in the NINA series. A design that should be pin compatible with other NINA-series modules should keep the VCC and VCC_IO supply rails separate. 2.2 RF antenna interfaces 2.2.1 2.4 GHz Bluetooth low energy (ANT) The three NINA-B3 model versions have their own 2.4 GHz antenna solutions respectively:  The NINA-B311 modules provide an antenna pin (ANT) with a nominal characteristic impedance of 50 Ω. This pin can be connected to an onboard antenna or antenna connector using a controlled impedance trace.  The NINA-B312 modules use an integrated antenna solution; no additional components are required. The antenna is a metal sheet PIFA antenna that makes the module insensitive to placement on the carrier board or the size of the carrier board, when compared to other integrated antenna solutions. The ANT pin is internally disconnected on these models. 2.2.2 Near Field Communication (NFC) The NINA-B3 series modules include a Near Field Communication interface, capable of operating as a 13.56 MHz NFC tag at a bit rate of 106 kbps. As an NFC tag, the data can be read from or written to the NINA-B3 modules using an NFC reader; however, the NINA-B3 modules are not capable of reading other tags or initiating NFC communications. The NFC interface can be used to wake the module from sleep mode, meaning that the module can be kept in the deepest power save mode and wake up and properly react to an NFC field. Two pins are available for connecting to an external NFC antenna: NFC1 and NFC2.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 13 of 50 2.3 System functions The NINA-B3 series modules are power efficient devices capable of operating in different power saving modes and configurations. Different sections of the module can be powered off when not needed and complex wake- up events can be generated from different external and internal inputs. The radio part of the module operates independently from the CPU. The three main power modes are:  Active  Standby  Sleep Depending on the application, the module should spend most of its time in either standby or sleep mode to minimize current consumption. 2.3.1 Module power-on You can switch on or reboot the NINA-B3 modules in one of the following ways:  Rising edge on the VCC pin to a valid supply voltage  Issuing a reset of the module (see section 2.3.5) An event to wake up from the sleep mode to the active mode can be triggered by:  A programmable digital or analog sensor event. For example, rising voltage level on an analog comparator pin  Detecting an NFC field  Supplying 5 V to the VBUS pin (plugging in the USB interface) While waking up from the standby mode to active mode, an event can also be triggered by:  The on-board Real Time Counter (RTC)  The radio interface 2.3.2 Module power off There is no dedicated pin to power off the NINA-B3 modules. You can configure any GPIO pin to enter or exit the sleep mode (see section 2.3.4), which essentially powers down the module. An under-voltage (brown-out) shutdown occurs on the NINA-B3 modules when the VCC supply drops below the operating range minimum limit. If this occurs, it is not possible to store the current parameter settings in the module’s non-volatile memory. An over temperature and under temperature shutdown can be enabled on the NINA-B3 modules, and is initiated if the temperature measured within the module is outside operating conditions. The temperature is measured by an integrated temperature sensor in the radio chip. 2.3.3 Standby mode Standby mode is one of the power saving modes in NINA-B3 modules that essentially powers down the module but keeps the system RAM and configurations intact. It also allows for complex, autonomous power-up events including periodic RTC events and radio events. The following events can be used to bring the module out of the standby mode:  Internal wake-up events from the RTC, radio, NFC and so on.  Analog or digital sensor events (programmable voltage level or edge detection) During standby mode, the module is clocked at 32 kHz, which is generated by an internal 32 kHz crystal oscillator.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 14 of 50 2.3.4 Sleep mode Sleep mode is the deepest power saving mode of NINA-B3 modules. During sleep mode, all functionality is stopped to ensure minimum power consumption. The module needs an external event in order to wake up from the sleep mode. The module will always reboot after waking up from the sleep mode; however different sections of the RAM can be configured to remain intact during and after going to the sleep mode. The following events can be used to wake up the module out of the sleep mode:  External event on a digital pin  External analog event on a low power comparator pin  Detection of an NFC field When using the u-blox connectivity software, the module can be manually switched on or off with proper storage of the current settings using the UART DSR pin. The module can be programmed to latch the digital values present at its GPIO pins during sleep. The module will keep the values latched, and a change of state on any of these pins will trigger a wake-up to active mode. 2.3.5 Module reset You can reset the NINA-B3 modules using one of the following ways:  Low level on the RESET_N input pin, normally kept high using an internal pull-up. This causes an “external” or “hardware” reset of the module. The current parameter settings are not saved in the module’s non-volatile memory and a proper network detach is not performed.  Using the AT+CPWROFF command. This causes an “internal” or “software” reset of the module. The current parameter settings are saved in the module’s non-volatile memory and a proper network detach is performed. 2.3.6 CPU and memory The Nordic Semiconductor nRF52840 chip in the NINA-B3 series modules includes a powerful Arm Cortex M4 processor. The processor works with a superset of 16 and 32-bit instructions (Thumb-2) at 64 MHz clock speed. It can use up to 37 interrupt vectors and 3 priority bits. The nRF52840 chip has 1 MB of flash and 256 KB of RAM for code and data storage. Additionally, up to 4 GB of external memory can be addressed with Execute in Place (XIP) support via the QSPI interface. See Section 2.4.3 for additional information. 2.3.7 Direct Memory Access All interfaces described in this data sheet support Direct Memory Access (DMA) to move any data generated from the interface directly into the RAM, without involving the CPU. This ensures fluent operation of the CPU with minimal need for interruption. To reduce the overall power consumption, DMA should be used as often as possible. 2.3.8 Programmable Peripheral Interconnect The Nordic Semiconductor nRF52840 chip in the NINA-B3 series modules include a programmable peripheral interconnect (PPI), which is basically a switch matrix that connects various control signals between different interfaces and system functions. This allows most interfaces to bypass the CPU in order to trigger a system function, that is, an incoming data packet may trigger a counter or a falling voltage level on an ADC, might toggle a GPIO, all without having to send an interrupt to the CPU. This enables smart applications that are extremely power efficient that wake up the CPU only when it is needed.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 15 of 50 2.3.9 Real Time Counter (RTC) A key system feature available on the module is the Real Time Counter. This counter can generate multiple interrupts and events to the CPU and radio as well as internal and external hardware blocks. These events can be precisely timed ranging from microseconds up to hours, and allows for periodic BLE advertising events etc., without involving the CPU. The RTC can be operated in the active and standby modes. 2.4 Serial interfaces NINA-B3 modules provide the following serial communication interfaces:  2x UART interfaces: 4-wire universal asynchronous receiver/transmitter interface used for AT command interface, data communication, and u-blox connectivity software upgrades using the Software update+UFWUPD AT command.  3x SPI interfaces: Up to three serial peripheral interfaces can be used simultaneously.  1x QSPI interface: High speed interface used to connect to the external flash memories.  2x I2C interfaces: Inter-Integrated Circuit (I2C) interface for communication with digital sensors.  1x I2S interface: Used to communicate with external audio devices.  1x USB 2.0 interface: The USB device interface to connect to the upstream host. ☞ Most digital interface pins on the module are shared between the digital, analog interfaces and GPIOs. Unless otherwise stated, all functions can be assigned to any pin that is not already occupied. ☞ Two of the SPI interfaces share common hardware with the I2C interfaces and they cannot be used simultaneously. That is, if both the I2C interfaces are in use then only one SPI interface will be available. 2.4.1 Universal Asynchronous Receiver/Transmitter (UART) The 4-wire UART interface supports hardware flow control and baud rates up to 1 Mbps. Other characteristics of the UART interface are listed below:  Pin configuration: o TXD, data output pin o RXD, data input pin o RTS, Request To Send, flow control output pin (optional) o CTS, Clear To Send, flow control input pin (optional)  Hardware flow control or no flow control (default) is supported.  Power saving indication available on the hardware flow control output (RTS pin): The line is driven to the OFF state when the module is not ready to accept data signals.  Programmable baud rate generator allows most industry standard rates, as well as non-standard rates up to 1 Mbps.  Frame format configuration: o 8 data bits o Even or no-parity bit o 1 stop bit  Default frame configuration is 8N1, meaning eight (8) data bits, no (N) parity bit, and one (1) stop bit.  Frames are transmitted in such a way that the least significant bit (LSB) is transmitted first.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 16 of 50 2.4.2 Serial peripheral interface (SPI) NINA-B3 supports up to three Serial Peripheral Interfaces with serial clock frequencies of up to 8 MHz. Characteristics of the SPI interfaces are listed below:  Pin configuration in master mode: o SCLK, Serial clock output, up to 8 MHz o MOSI, Master Output Slave Input data line o MISO, Master Input Slave Output data line o CS, Chip/Slave select output, active low, selects which slave on the bus to talk to. Only one select line is enabled by default but more can be added by customizing a GPIO pin. o DCX, Data/Command signal, this signal is optional but is sometimes used by the SPI slaves to distinguish between SPI commands and data  Pin configuration in slave mode: o SCLK, Serial clock input o MOSI, Master Output Slave Input data line o MISO, Master Input Slave Output data line o CS, Chip/Slave select input, active low, connects/disconnects the slave interface from the bus.  Both master and slave modes are supported on all the interfaces.  The serial clock supports both normal and inverted clock polarity (CPOL) and data should be captured on rising or falling clock edge (CPHA). 2.4.3 Quad serial peripheral interface (QSPI) The Quad Serial Peripheral Interface enables external memory to be connected to the NINA-B3 module to increase the application program size. The QSPI supports Execute In Place (XIP), which allows CPU instructions to be read and executed directly from the external memory (128 MB at a time with a programmable offset). Characteristics for the QSPI are listed below:  The QSPI always operates in master mode and uses the following pin configuration: o CLK, serial clock output, up to 32 MHz o CS, Chip/Slave select output, active low, selects which slave on the bus to talk to o D0, MOSI serial output data in single mode, data I/O signal in dual/quad mode o D1, MISO serial input data in single mode, data I/O signal in dual/quad mode o D2, data I/O signal in quad mode (optional) o D3, data I/O signal in quad mode (optional)  Single/dual/quad read and write operations (1/2/4 data signals)  Clock speeds between 2 – 32 MHz  Data rates up to 128 Mbit/s in the quad mode  32 bit addressing can address up to 4 GB of data  Instruction set includes support for deep power down mode of the external flash  Possible to generate custom flash instructions containing a 1 byte opcode and up to 8 bytes of additional data and read its response 2.4.4 I2C interface The Inter-Integrated Circuit interfaces can be used to transfer and/or receive data on a 2-wire bus network. The NINA-B3 modules can operate as both master and slave on the I2C bus using standard (100 kbps), fast (400 kbps), and 250 kbps transmission speeds. The interface supports clock stretching, thus allowing NINA-B3 to temporarily pause any I2C communications. Up to 127 individually addressable I2C devices can be connected to the same two signals.  Pin configuration: o SCL, clock output in master mode, input in slave mode
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 17 of 50 o SDL, data input/output pin This interface requires external pull-up resistors to work properly in the master mode; see section 4.2.7 for suggested resistor values. The pull-up resistors are required in the slave mode as well but should be placed at the master end of the interface. 2.4.5 I2S interface The Inter-IC Sound (I2S) interface can be used to transfer audio sample streams between NINA-B3 and external audio devices such as codecs, DACs, and ADCs. It supports original I2S and left or right-aligned interface formats in both master and slave modes.  Pin configuration: o MCK, Master clock o LRCK, Left Right/Word/Sample clock o SCK, Serial clock o SDIN, Serial data in o SDOUT, Serial data out The Master side of an I2S interface always provides the LRCK and SCK clock signals, but some master devices cannot generate a MCK clock signal. NINA-B3 can supply a MCK clock signal in both master and slave modes to provide to those external systems that cannot generate their own clock signal. The two data signals - SDIN and SDOUT allow for simultaneous bi-directional audio streaming. The interface supports 8, 16, and 24-bit sample widths with up to 48 kHz sample rate. 2.4.6 USB 2.0 interface The NINA-B3 series modules include a full speed Universal Serial Bus (USB) device interface which is compliant to version 2.0 of the USB specification. Characteristics of the USB interface include:  Full speed device, up to 12 Mbit/s transfer speed  MAC and PHY implemented in the hardware  Pin configuration: o VBUS, 5 V supply input, required to use the interface o USB_DP, USB_DM, differential data pair  Automatic or software controlled pull-up of the USB_DP pin The USB interface has a dedicated power supply that requires a 5 V supply voltage to be applied to the VBUS pin. This allows the USB interface to be used even though the rest of the module might be battery powered or supplied by a 1.8 V supply etc. 2.5 Digital interfaces 2.5.1 PWM The NINA-B3 modules provide up to 12 independent PWM channels that can be used to generate complex waveforms. These waveforms can be used to control motors, dim LEDs, or as audio signals if connected to the speakers. Duty-cycle sequences may be stored in the RAM to be chained and looped into complex sequences without CPU intervention. Each channel uses a single GPIO pin as output. 2.5.2 PDM The pulse density modulation interface is used to read signals from external audio frontends like digital microphones. It supports single or dual-channel (left and right) data input over a single GPIO pin. It supports up to 16 kHz sample rate and 16 bit samples. The interface uses the DMA to automatically move the sample data into RAM without CPU intervention. The interface uses two signals - CLK to output the sample clock and DIN to read the sample data.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 18 of 50 2.5.3 QDEC The quadrature decoder is used to read quadrature encoded data from mechanical and optical sensors in the form of digital waveforms. Quadrature encoded data is often used to indicate rotation of a mechanical shaft in either a positive or negative direction. The QDEC uses two inputs - PHASE_A and PHASE_B, and an optional LED output signal. The interface has a selectable sample period ranging from 128 µs to 131 ms. 2.6 Analog interfaces 8 out of the 38 digital GPIOs can be multiplexed to analog functions. The following analog functions are available:  1x 8-channel ADC  1x Analog comparator*  1x Low-power analog comparator* *Only one comparator can be used at any given point of time. 2.6.1 ADC The Analog to Digital Converter (ADC) is used to sample an analog voltage on the analog function enabled pins of the NINA-B3. Any of the 8 analog inputs can be used. Characteristics of the comparator include:  Full swing input range of 0 V to VCC.  8/10/12-bit resolution  14-bit resolution while using oversampling  Up to 200 kHz sample rate  Single shot or continuous sampling  Two operation modes: Single-ended or Differential  Single-ended mode: o A single input pin is used  Differential mode: o Two inputs are used and the voltage level difference between them is sampled If the sampled signal level is much lower than the VCC, it is possible to lower the input range of the ADC to better encompass the wanted signal, and achieve a higher effective resolution. Continuous sampling can be configured to sample at a configurable time interval, or at different internal or external events, without CPU involvement. 2.6.2 Comparator The analog comparator compares the analog voltage on one of the analog enabled pins in NINA-B3 with a highly configurable internal or external reference voltage. Events can be generated and distributed to the rest of the system when the voltage levels cross. Further characteristics of the comparator include:  Full swing input range of 0 V to VCC.  Two operation modes: Single-ended or Differential  Single-ended mode: o A single reference level or an upper and lower hysteresis selectable from a 64-level reference ladder with a range from 0 V to VREF (described in Table 4)  Differential mode: o Two analog pin voltage levels are compared, optionally with a 50 mV hysteresis  Three selectable performance modes - High speed, balanced, or power save See section 4.2.8 for a comparison of the various analog comparator options.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 19 of 50 2.6.3 Low power comparator In addition to the power save mode available for the comparator, there is a separate low power comparator available on the NINA-B3 module. This allows for even lower power operation, at a slightly lower performance and with less configuration options. Characteristics of the low power comparator include:  Full swing input range of 0 to VCC.  Two operation modes - Single-ended or Differential  Single-ended mode: o The reference voltage LP_VIN- is selected from a 15-level reference ladder  Differential mode: o Pin GPIO_16 or GPIO_18 is used as reference voltage LP_VIN-  Can be used to wake the system from sleep mode See section 4.2.8 for the electrical specifications of the different analog comparator options. See Table 4 for a summary of the analog pin options. Since the run current of the low power comparator is very low, it can be used in the module sleep mode as an analog trigger to wake up the CPU. See section 2.3.4 for additional information. 2.6.4 Analog pin options Table 4 shows the supported connections of the analog functions. ☞ An analog pin may not be simultaneously connected to multiple functions. Table 4: Possible uses of the analog pins 2.7 GPIO The NINA-B3 series modules are versatile concerning pin-out. In an un-configured state, there will be 38 GPIO pins in total and no analog or digital interfaces. All interfaces or functions must then be allocated to a GPIO pin before use. 8 out of the 38 GPIO pins are analog enabled, meaning that they can have an analog function allocated to them. In addition to the serial interfaces, Table 5 shows the number of digital and analog functions that can be assigned to a GPIO pin. Symbol Analog function Can be connected to ADCP ADC single-ended or differential positive input Any analog pin or VCC ADCN ADC differential negative input Any analog pin or VCC VIN+ Comparator input Any analog pin VREF Comparator single-ended mode reference ladder input Any analog pin, VCC, 1.2 V, 1.8V or 2.4V VIN- Comparator differential mode negative input Any analog pin LP_VIN+ Low-power comparator IN+ Any analog pin LP_VIN- Low-power comparator IN- GPIO_16 or GPIO_18, 1/16 to 15/16 VCC in steps of 1/16 VCC

For additional information, see the u-blox Short Range AT Commands Manual [2]. 2.8.1 u-blox Serial Port Service (SPS) The serial port service feature enables serial port emulation over Bluetooth low energy. 2.8.2 System status signals The RED, GREEN, and BLUE pins are used to signal the system status as shown in Table 6. They are active low and are intended to be routed to an RGB LED. Mode Status RGB LED Color RED GREEN BLUE Data mode/Extended Data mode (EDM) IDLE Green HIGH LOW HIGH Command mode IDLE Orange LOW LOW HIGH EDM/Data mode, Command mode CONNECTING Purple LOW HIGH LOW EDM/Data mode, Command mode CONNECTED** Blue HIGH HIGH LOW * = LED flashes on data activity Table 6: System status indication ☞ The CONNECTING and CONNECTED statuses indicate u-blox SPS connections. 2.8.3 System control signals The following input signals are used to control the system:  RESET_N is used to reset the system. See section 2.3.5 for detailed information.  If SWITCH_2 is driven low during start up, the UART serial settings are restored to their default values.  The SWITCH_2 can be used to open a Bluetooth LE connection with a peripheral device.
NINA-B3 series - Data Sheet UBX-17052099 - R02 Interfaces Page 21 of 50  If both SWITCH_1 and SWITCH_2 are driven low during start up, the system will enter bootloader mode.  If both SWITCH_1 and SWITCH_2 are driven low during start up and held low for 10 seconds, the system will exit the bootloader mode and restore all settings to their factory default. 2.8.4 UART signals In addition to the normal RXD, TXD, CTS, and RTS signals, the u-blox connectivity software adds the DSR and DTR pins to the UART interface. Note that they are not used as originally intended, but to control the state of the NINA module. For example, depending on the current configuration: The DSR pin can be used to:  Enter the command mode  Disconnect and/or toggle connectable status  Enable/disable the rest of the UART interface  Enter/wake up from the sleep mode The DTR pin can be used to indicate:  The System mode  If the SPS peers are connected  If a Bluetooth LE bonded device is connected  A Bluetooth LE GAP connection ☞ See the u-blox Short Range AT Commands Manual [2] for more information. 2.9 Debug interfaces 2.9.1 SWD The NINA-B30 series modules provide an SWD interface for flashing and debugging. The SWD interface consists of two pins - SWDCLK and SWDIO. The SWD interface is disabled on the NINA-B31 series modules. 2.9.2 Trace – Serial Wire Output A serial trace option is available on the NINA-B30 series modules as an additional pin- SWO. The Serial Wire Output (SWO) is used to:  Support printf style debugging  Trace OS and application events  Emit diagnostic system information A debugger that supports Serial Wire Viewer (SWV) is required. 2.9.3 Parallel Trace The NINA-B30 series modules support parallel trace output as well. This allows output from the Embedded Trace Macrocell (ETM) and Instrumentation Trace Macrocell (ITM) embedded in the Arm Cortex-M4 core of the nRF52840 chip in the NINA-B3. The ETM trace data allows a user to record exactly how the application goes through the CPU instructions in real time. The parallel trace interface uses 1 clock signal and 4 data signals respectively - TRACE_CLK, TRACE_D0, TRACE_D1, TRACE_D2 and TRACE_D3.

A = Analog function capable pin Figure 3: NINA-B30 series pin assignment (top view) The grey pins in the center of the modules are GND pins. The outline of NINA-B301 ends at the dotted line as shown in Figure 3, where the antenna area of the NINA-B302 begins. ☞ Most of the digital or analog functions described in this data sheet may be freely assigned to any GPIO pin. Analog functions are limited to analog capable pins. Signals that are highlighted in red in Figure 3 are not freely assignable but locked to a specific pin. ☞ The GPIO pins - 16, 17, 18 and 20 are connected to the pins located close to the radio part of the RF chip. It is recommended to avoid using these pins for high speed digital interfaces or sinking/sourcing large currents through them. Doing so may affect the RF performance. ⚠ Do not apply an NFC field to the NFC pins when they are configured as GPIOs as this can cause permanent damage to the module. When driving different logic levels on these pins in the GPIO mode, a small current leakage will occur. Ensure that they are set to the same logic level before entering into any power saving modes. See section 4.2.6 for more information.

NINA-B3 series - Data Sheet UBX-17052099 - R02 Qualification and approvals Page 40 of 50  Any notification to the end user about how to install or remove the integrated radio module is NOT allowed.  The modular transmitter approval of NINA-B3 does not exempt the end-product from being evaluated against applicable regulatory demands. The evaluation of the end-product shall be performed with the NINA-B3 module installed and operating in a way that reflects the intended end-product use case. The upper frequency measurement range of the end product evaluation is the 5th harmonic of 2.4 GHz as declared in 47 CFR Part 15.33 (b)(1).  The following requirements apply to all products that integrate a radio module: o Subpart B - UNINTENTIONAL RADIATORS To verify that the composite device of host and module complies with the requirements of FCC part 15B the integrator shall perform sufficient measurements using ANSI 63.4-2014. o Subpart C - INTENTIONAL RADIATORS It is required that the integrator carry out sufficient verification measurements using ANSI 63.10-2013 to validate that the fundamental and out of band emissions of the transmitter part of the composite device complies with the requirements of FCC part 15C.  When the items listed above are fulfilled the host manufacturer can use the authorization procedures presented in Table 1 of 47 CFR Part 15.101. 6.2.5.2 Co-location (simultaneous transmission) If the module is to be co-located with another transmitter, additional measurements for simultaneous transmission are required. 6.2.5.3 802.15.4 channel map limitation (NINA-B30 series only) The 2.4 GHz band used by 802.15.4 communications is segmented into 15 channels, ranging from channel 11 at 2405 MHz to channel 26 at 2480 MHz, with 5 MHz channel spacing. Due to the wide spectral properties of the 802.15.4 signal, the use of channel 26 results in too much power being transmitted in the FCC restricted band starting at 2483.5 MHz. Integrators of the NINA-B30 series will have to make a “change in FCC ID” filing to inherit the test results of the u-blox FCC compliance tests. In this filing process it must be made clear that the SW application has been limited to not use channel 26, and that it cannot be ‘unlocked’ by an end-user. It should also not be possible for an end-user to change the SW on the module to any un-authorized or modified SW that allows the use of 802.15.4 channel 26. 6.3 Safety Compliance In order to fulfill the safety standard EN 60950-1, the NINA-B3 series modules must be supplied with a Class-2 Limited Power Source. 6.4 Bluetooth qualification information ☞ Bluetooth qualifications are pending.
