1 Functional description

1.1 Overview

The NINA-B1 stand-alone Bluetooth low energy (Bluetooth Smart) module is a compact module with very low

power consumption and is suitable for applications using coin cell batteries. The Bluetooth low energy stack is

embedded in the module. This module is offered in professional grade for applications such as health care, asset

tracking, connected cities, home automation, smart energy, manufacturing and telematics. It offers Apple iOS

and Google Android connectivity for applications requiring this. The NINA-B1 embeds firmware with the u-blox

Serial Port Service for replacing serial cables or accessing UART devices using Bluetooth low energy technology.

The NINA-B1 is tailored for those who wish to embed a customer developed application and/or Bluetooth

services/attributes on top of the integrated software stack and tools. The NINA-B1 is a stand-alone product with

no additional hardware required. Additional sensors such as temperature sensor, accelerometers, LEDs etc., can

be connected directly to the module. The NINA-B1 sample code package includes sample projects for accessing

the LEDs, temperature sensor, accelerometers etc., on the application board.

The modules are fully Bluetooth qualified and provide global modular approval. They are also compliant with

safety and medical standards.

1.3.1 NINA-B111

The NINA-B111 modules do not use the internal antenna and thus the PCB has been trimmed to allow for a

smaller module (10.0 x 10.6 mm). Instead of an internal antenna, the RF signal is available at a module pin for

routing to an external antenna or antenna connector.

1.3.2 NINA-B112

The NINA-B112 modules use an integrated antenna mounted on the PCB (10.0 x 14.0 mm). The RF signal pin is

not connected to any signal path.

2 Interfaces

2.1 Power management

2.1.1 Module supply input (VCC)

The NINA-B1 series uses an integrated DC/DC converter to transform the supply voltage presented at the VCC

pin into a stable system voltage. Due to this, the NINA-B1 modules are compatible for use in battery powered

designs.

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.

On the NINA-B1 series modules, the I/O voltage level is the same as the supply voltage and VCC_IO is internally

connected to the supply input. Therefore only a single supply voltage is needed for NINA-B1, which makes it

ideal for battery powered designs.

This may not be the case for modules in the NINA series that will be released in the future. 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 two NINA-B1 model versions have their own 2.4 GHz antenna solutions respectively:

 The NINA-B111 modules provide an antenna pin (ANT) with a nominal characteristic impedance of 50

Ω. This pin can be connected to an on-board antenna or antenna connector using a controlled

impedance trace. See the NINA-B1 series System Integration Manual [1] for more information.

 The NINA-B112 modules use an integrated antenna solution; no additional components are required.

The ANT pin is internally disconnected on these models.

2.2.2 Near Field Communication (NFC)

The NINA-B1 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, data can be read from or written to the NINA-B1 modules

using an NFC reader; however the NINA-B1 modules are not capable of reading other tags or initiating NFC

communications. Two pins are available for connecting to an external NFC antenna: NFC1 and NFC2. See the

NINA-B1 series System Integration Manual [1] for more information and NFC antenna design considerations.

2.3 System functions

The NINA-B1 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 two main power saving modes are:

 Standby mode

 Sleep mode

Depending on the application, the module should spend most of its time in sleep mode to conserve battery life.

2.3.1 Module power-on

NINA-B1 modules can be switched on in one of the following ways and this will cause the module to reboot:

 Rising edge on the VCC pin to a valid supply voltage

NINA-B1 series - Data Sheet

UBX-15019243 - R05 Early Production Information Interfaces

Page 10 of 35

 Issuing a reset of the module

A wake up event from sleep mode to active mode can be issued by:

 Changing the state of any digital I/O pin, may be enabled /disabled for each pin.

If waking up from standby mode, an event can also be issued by:

 The on-board Real Time Counter (RTC)

 A programmable digital or analog sensor event. For example, rising voltage level on an analog

comparator pin

2.3.2 Module power-off

There is no dedicated pin to power off the NINA-B1 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 NINA-B1 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

NINA-B1 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. For more details

see the NINA-B1 series System Integration Manual [1].

2.3.3 Standby mode

Standby mode is one of the power saving modes in NINA-B1 modules that essentially powers down the module

but keeps the system RAM intact and allows for a few low power digital interfaces (including SPI) and analog

functions to run continuously. It also allows for more 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:

 External wake-up events

 Internal wake-up events from RTC, radio, NFC and so on

 Analog or digital sensor event (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.

2.3.4 Sleep mode

Sleep mode is the deepest power saving mode of NINA-B1 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

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 event on a low power comparator pin

 Detection of NFC field

When using the NINA-B11x firmware, the module can be manually switched on or off with proper storage of

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.

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 into the sleep mode.

2.3.5 Module reset

NINA-B1 modules can be reset in one of the following ways:

NINA-B1 series - Data Sheet

UBX-15019243 - R05 Early Production Information Interfaces

Page 11 of 35

 Low level on the RESET_N input pin, normally high with 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 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 main CPU. The RTC can be operated in power-on and standby modes.

2.4 Serial interfaces

NINA-B1 modules provide the following serial communication interfaces:

 1x UART interface: 4-wire unbalanced asynchronous serial interface used for AT commands interface,

data communication and firmware upgrades using the FOAT feature.

 3x SPI interfaces: Up to three serial peripheral interfaces can be used simultaneously.

 2x I2C interfaces: Inter-Integrated Circuit (I2C) interface for communication with digital sensors.

All digital interface pins on the module are shared between the digital and analog interfaces and GPIOs.

Any function can be assigned to any pin that is not already occupied.

2.4.1 Asynchronous serial interface (UART)

The UART interface supports hardware flow control and baud-rates up to 1 Mbps. Other characteristics of the

UART interface are listed below:

 Data lines (RXD as input, TXD as output) and hardware flow control lines (CTS as input, RTS as output)

are provided.

 Hardware flow control or no flow control (default) is supported.

 Power saving indication available on the hardware flow control output (CTS line): 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.

2.4.2 Serial peripheral interface (SPI)

NINA-B1 supports up to 3 Serial Peripheral Interfaces that can operate in both master and slave mode with a

maximum serial clock frequency of 8 MHz in both master and slave modes. The SPI interfaces use 4 signals:

SCLK, MOSI, MISO and CS. When using the SPI interface in master mode, it is possible to use GPIOs as

additional Chip Select (CS) signals to allow addressing of multiple slaves.

2.4.3 I2C interface

The Inter-Integrated Circuit interfaces can be used to transfer or receive data on a 2-wire bus network. The

NINA-B1 modules can operate as both master and slave on the I2C bus using both standard (100 kbps) and fast

(400 kbps) transmission speeds. The interface uses the SCL signal to clock instructions and data on the SDL

signal.

2.5 GPIO

The NINA-B1 modules are versatile concerning pin-out. If un-configured, there will be 19 GPIO pins in total and

no analog or digital interfaces. All digital interfaces or functions must then be allocated to a GPIO pin before use.

7 out of the 19 GPIO pins are analog enabled thus they can have an analog function allocated to them. In

addition to the serial interfaces, Table 4 shows the number of digital and analog functions that can be assigned

to a GPIO pin.

This list is not final, and functions may be added or removed without notice.

available for use:

 1x 8-channel ADC

 1x Analog comparator*

 1x Low-power analog comparator*

*Only one of the comparators can be used simultaneously.

2.6.1 ADC

The Analog to Digital Converter (ADC) can sample up to 200 kHz using different inputs as sample triggers. It

supports 8/10/12-bit resolution. Any of the 8 analog inputs can be used both as single-ended inputs and as

differential pairs for measuring the voltage across them. The ADC supports full 0 V to VCC input range.

2.6.2 Comparator

The comparator compares voltages from any analog pin with different references as shown in Table 5. It

supports full 0 V to VCC input range and can generate different software events to the rest of the system.

2.6.3 Low power comparator

The low-power comparator operates in the same way as the normal comparator, with some reduced

functionality. It can be used during sleep mode as a wake up source.

 SWITCH_1 is used to enter the bootloader or to restore the UART serial settings to their default values.

 SWITCH_2 can be used to open a BLE connection to a peripheral device.

 If both SWITCH_1 and SWITCH_2 are driven low during start up, the system will restore all settings to

their factory defaults.

2.7.3 UART signals

In addition to the normal RXD, TXD, CTS, and RTS signals, the NINA-B11x firmware 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. Depending on the current configuration, the DSR can be used to:

 Enter command mode

 Disconnect and/or toggle connectable status

 Enable/disable the rest of the UART interface

 Enter/wake up from sleep mode

3.1 Pin assignment

The pin-out described in Figure 2 below is an example pin-out that shows the module in an unconfigured state.

Alternatively, if you use the u-blox NINA-B11x firmware, refer to the pin-out in section 3.2.

A = Analog function capable pin

Figure 2: NINA-B1 series pin assignment (top view)

All 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 marked red in Figure 2 are not freely assignable but

locked to a specific pin.

GPIO pins 16, 17, 18 and 20 are connected to 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 RF performance.

Do not apply an NFC field to the NFC pins when they are configured as GPIOs as it can cause

permanent damage to the module. When driving different logic levels on these pins in GPIO mode, a

small current leakage will occur. Ensure that they are set to the same logic level before entering into any
