SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Functional description Page 5 of 41 1 Functional description 1.1 Overview SARA-R4/N4 series modules are an LTE Cat M1, LTE Cat NB1 and EGPRS multi-mode solution in the miniature SARA LGA form factor (26.0 x 16.0 mm, 96-pin). They allow an easy integration into compact designs and a seamless drop-in migration from other u-blox cellular module families. SARA-R4/N4 series modules provide software-based multi-band configurability enabling world-wide global coverage in LTE Cat M1 / NB1 and (E)GPRS / GSM radio access technologies. Variants specifically designed to operate in LTE Cat NB1 only, or in LTE Cat M1 band 13 only, or in LTE Cat M1 bands 2, 4, 5 and 12 only are also available. SARA-R4/N4 series modules offer data communications up to 375 kbit/s over an extended operating temperature range of –40 °C to +85 °C, with low power consumption, and with coverage enhancement for deeper range into buildings and basements (and underground with NB1). With many interface options and an integrated IP stack, SARA-R4/N4 series modules are the optimal choice for LPWA applications with low to medium data throughput rates, as well as devices that require long battery lifetimes, such as used in smart metering, smart lighting, telematics, asset tracking, remote monitoring, alarm panels, and connected health. Customers can future-proof their solutions by means of Over-The-Air firmware updates, thanks to the uFOTA client/server solution that utilizes LWM2M, a light and compact protocol ideal for IoT applications. SARA-R4/N4 series modules will also support VoLTE over Cat M1. The flexibility extends further through dynamic mode selection as M1-only/preferred or NB1-only/preferred. 1.2 Product features Model Region Bands Positioning Interfaces Audio Features Grade 3GPP Release Baseline 3GPP LTE category LTE FDD bands GSM/(E)GPRS 4-band GNSS via modem AssistNow software CellLocate® UART USB 2.0 SPI SDIO DDC (I2C) GPIOs Analog audio Digital audio Power Saving Mode eDRX Antenna supervisor Embedded TCP/UDP stack Embedded HTTP, FTP Dual stack IPv4/IPv6 FW update over the air (FOTA) Standard Professional Automotive SARA-R404M USA 13 M1 13 ● ● ● ● ● ● ● ● ● ● SARA-R410M-01B North America 13 M1 2,4 5,12 ● ● ● ● ● ● ● ● ● ● SARA-R410M-02B Global 13 M1 NB1 * ● ● ○ ● ● ○ ○ ● ● ○ ● ● ● ● ● ● ● ● SARA-R412M-02B Global 13 M1 NB1 * ● ● ● ○ ● ● ○ ○ ● ● ○ ● ● ● ● ● ● ● ● SARA-N410-02B Global 13 NB1 * ● ● ○ ● ● ○ ○ ● ● ● ● ● ● ● ● ● ● * = Bands 1, 2, 3, 4, 5, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28 (and band 39 in M1-only) ● = supported by all FW versions ○ = supported by future FW versions Table 1: SARA-R4/N4 series main features summary

SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 9 of 41 1.6 Supported features Table 3 lists some of the main features supported by SARA-R4/N4 series modules. For more details, see the SARA-R4/N4 series System Integration Manual [2] and the SARA-R4/N4 series AT Commands Manual [1]. Feature Description Network Indication GPIO configured to indicate the network status: registered home network, registered roaming, data call enabled, no service. The feature can be enabled through the +UGPIOC AT command. Antenna Detection The ANT_DET pin provides antenna presence detection capability, evaluating the resistance from the ANT pin to GND by means of an external antenna detection circuit implemented on the application board. The antenna supervisor (i.e. antenna detection) feature can be enabled through the +UANTR AT command. Embedded TCP and UDP stack Embedded TCP/IP and UDP/IP stack including direct link mode for TCP and UDP sockets. Sockets can be set in Direct Link mode to establish a transparent end-to-end communication with an already connected TCP or UDP socket via the serial interface. FTP File Transfer Protocol functionality is supported via AT commands. HTTP Hyper-Text Transfer Protocol functionality is supported via AT commands. Embedded SSL/TLS 4 With the support of X.509 certificates, embedded SSL/TLS provides server and client authentication, data encryption, data signature and enables TCP/IP applications to communicate over a secured and trusted connection. The feature can be configured and enabled by the +USECMNG and +USECPRF AT commands. MQTT 5 Message Queuing Telemetry Transport is an ISO standard publish-subscribe messaging protocol designed for lightweight M2M communications over TCP. MQTT allows clients to communicate one-to-one, one-to-many and many-to-one over a long-lived outgoing TCP connection. Dual stack IPv4/IPv6 Capability to move between IPv4 and dual stack network infrastructures. IPv4 and IPv6 addresses can be used. Firmware update Over AT commands (FOAT) Firmware module update over AT command interface. The feature can be enabled and configured through the +UFWUPD AT command. Firmware update Over The Air (uFOTA) u-blox firmware module update over the LTE air interface client/server solution using LWM2M. GNSS via modem 5 Full access to u-blox positioning chips and modules is available through a dedicated DDC (I2C) interface. This means that from any host processor, a single serial port can control the SARA-R4/N4 series cellular module and the u-blox positioning chip or module. Power Saving Mode (PSM) The Power Saving Mode (PSM) feature, defined in 3GPP Rel.13, allows further reduction of the module current consumption maximizing the amount of time a device can remain in PSM low power deep sleep mode during periods of data inactivity. It can be activated and configured by the +CPSMS AT command. e-I-DRX 6 Extended Idle mode DRX, based on 3GPP Rel.13, reduces the amount of signaling overhead decreasing the frequency of scheduled measurements and/or transmissions performed by the module in idle mode. This in turn leads to a reduction in the module power consumption while maintaining a perpetual connection with the base station. Coverage Enhancements Mode A Coverage Enhancements Mode A, introduced in 3GPP Rel.13, is used to improve cell signal penetration. Coverage Enhancements Mode B 7 Coverage Enhancements Mode B, introduced in 3GPP Rel.13, is used to further improve cell signal penetration.

SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 10 of 41 2.1 Power management 2.1.1 Module supply input (VCC) SARA-R4/N4 series modules must be supplied through the VCC pins by a DC power supply. Voltage must be stable, because during operation the current drawn from VCC may vary significantly, based on the power consumption profile of the LTE Cat M1, LTE Cat NB1 and the 2G radio access technologies (described in the SARA-R4/N4 series System Integration Manual [2]). SARA-R412M modules provide separate supply inputs over the three VCC pins:  VCC pins #52 and #53 represent the supply input for the internal RF Power Amplifier, demanding most of the total current drawn of the module when RF transmission is enabled during a call  VCC pin #51 represents the supply input for the internal baseband Power Management Unit, demanding minor part of the total current drawn of the module when RF transmission is enabled during a call The three VCC pins of SARA-R404M, SARA-R410M and SARA-N410 modules are internally connected to both the internal Power Amplifier and the internal baseband Power Management Unit. It is important that the system power supply circuit is able to withstand the maximum pulse current during a transmit burst at maximum power level (see Table 12). 2.1.2 Generic digital interfaces supply output (V_INT) SARA-R4/N4 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when the module is switched on. The same voltage domain is used internally to supply the generic digital interfaces of the module. The V_INT supply output can be used in place of an external discrete regulator. 2.2 Antenna interface 2.2.1 Antenna RF interface (ANT) The ANT pin represents the RF antenna interface of the module, with a characteristic impedance of 50 . 2.2.2 Antenna detection (ANT_DET) The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by SARA-R4/N4 series modules to sense the antenna presence (as an optional feature). It evaluates the resistance from the ANT pin to GND by means of an external antenna detection circuit implemented on the application board (for more details, see the u-blox SARA-R4/N4 series System Integration Manual [2] and the SARA-R4/N4 series AT Commands Manual [1]).
SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 11 of 41 2.3 System functions 2.3.1 Module power-on SARA-R4/N4 series can be switched on using the following procedure:  Low level on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time period when the applied VCC voltage is within the valid operating range (see sections 4.2.3 and 4.2.8). The PWR_ON line has to be driven by open drain, open collector or contact switch. 2.3.2 Module power-off SARA-R4/N4 series can be properly switched off, with storage of the current parameter settings and a clean network detach, in one of these ways:  AT+CPWROFF command (see the SARA-R4/N4 series AT Commands Manual [1])  Low pulse on the PWR_ON pin for a valid time period (see section 4.2.8) An abrupt shutdown occurs on SARA-R4/N4 series modules, without storage of the current parameter settings and without a clean network detach, when:  the VCC supply drops below the extended operating range minimum limit  a low level is applied on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.9). RESET_N line has to be driven by open drain, open collector or contact switch. 2.3.3 Module reset SARA-R4/N4 series modules can be reset (re-booted) by:  AT+CFUN command (see the SARA-R4/N4 series AT Commands Manual [1]). 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 clean network detach is performed. 2.4 SIM 2.4.1 SIM interface A SIM card interface is provided on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins: the high-speed SIM/ME interface is implemented as well as the automatic detection of the required SIM supporting voltage. Both 1.8 V and 3 V SIM types are supported (1.8 V and 3 V). Activation and deactivation with an automatic voltage switch from 1.8 V to 3 V is implemented according to the ISO-IEC 7816-3 specifications. The SIM driver supports the PPS procedure for baud-rate selection, according to the values proposed by the SIM card/chip. 2.4.2 SIM detection The GPIO5 pin of SARA-R4/N4 series modules is a 1.8 V digital input which can be configured as an external interrupt to detect the SIM card presence, as intended to be properly connected to the mechanical switch of an external SIM card holder. For more details, see the SARA-R4/N4 series System Integration Manual [2] and the SARA-R4/N4 series AT Commands Manual [1].
SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 12 of 41 2.5 Serial communication The SARA-R4/N4 series provides the following serial communication interfaces:  UART interface: asynchronous serial interface available for the communication with a DTE host application processor (AT commands, data communication, FW update by means of FOAT)  USB interface: High-Speed USB 2.0 compliant interface available for communications with a USB host application processor (AT commands, data communication, FW update by means of the FOAT feature), for FW update by means of the u-blox tool and for diagnostics  SPI interface: Serial Peripheral Interface available for communications with an external compatible device  SDIO interface: Secure Digital Input Output interface available for communications with a compatible device  DDC interface: I2C bus compatible interface available for communications with external I2C devices 2.5.1 UART interface SARA-R4/N4 series modules include a 9-wire unbalanced asynchronous serial interface (UART) for communication with an application host processor (AT commands and data communication). ☞ The UART is available only if the USB is not enabled as AT command / data communication interface: UART and USB cannot be concurrently used for this purpose. UART features are:  Complete serial port with RS-232 functionality conforming to the ITU-T V.24 Recommendation [9], with CMOS compatible signal levels (0 V for low data bit or ON state and 1.8 V for high data bit or OFF state)  Data lines (RXD as output, TXD as input), hardware flow control lines (CTS as output, RTS as input), modem status and control lines (DTR as input, DSR as output, DCD as output, RI as output) are provided  The default baud rate is 115200 bit/s  The default frame format is 8N1 (8 data bits, no parity, 1 stop bit) ☞ Hardware flow control is not supported by the “00”, “01” and SARA-R410M-02B product versions, but the RTS input line needs to be set low (= ON state) to communicate over the UART interface on the “00” and “01” product versions. The UART serial interface can be conveniently configured through AT commands. For more details, see the SARA-R4/N4 series AT Commands Manual [1] and the SARA-R4/N4 series System Integration Manual [2]. Multiplexer protocol SARA-R4/N4 series modules include multiplexer functionality as per 3GPP TS 27.010 [6] on the UART physical link. This is a data link protocol which uses HDLC-like framing and operates between the module (DCE) and the application processor (DTE), allowing a number of simultaneous sessions over the physical link (UART).
SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 13 of 41 The following virtual channels are defined:  Channel 0: for Multiplexer control  Channel 1: for all AT commands, and non-Dial Up Network (non-DUN) data connections. UDP, TCP data socket / data call connections through relevant AT commands.  Channel 2: for Dial Up Network (DUN) data connection. It requires the host to have and use its own TCP/IP stack. The DUN can be initiated on the modem side or terminal/host side.  Channel 3: for u-blox GNSS data tunneling (not supported by the “00” and “01” product versions). 2.5.2 USB interface SARA-R4/N4 series modules include a high-speed USB 2.0 compliant interface with a maximum 480 Mbit/s data rate according to the USB 2.0 specification [10] representing the main interface for transferring high speed data with a host application processor. The module itself acts as a USB device and can be connected to any USB host equipped with compatible drivers. The USB is the most suitable interface for transferring high speed data between SARA-R4/N4 series and a host processor, available for AT commands, data communication, FW upgrade by means of the FOAT feature, FW upgrade by means of the u-blox dedicated tool and for diagnostic purposes. The USB_D+ / USB_D- lines carry the USB data and signaling, while the VUSB_DET pin represents the input to enable the USB interface by applying an external valid USB VBUS supply voltage (5.0 V typical). ☞ The USB interface is available as an AT command / data communication interface only if an external valid USB VBUS supply voltage (5.0 V typical) is applied at the VUSB_DET input of the module since the switch-on of the module, and then held during normal operations. In this case, the UART will not be available. ☞ If the USB interface is enabled, the module does not enter the low power deep sleep mode: the external USB VBUS supply voltage needs to be removed from the VUSB_DET input of the module to let it enter the Power Saving Mode defined in 3GPP Rel.13. SARA-R4/N4 series modules provide by default a set of two USB functions:  AT commands and data communication  Diagnostic log For more details regarding USB configurations / capabilities, see the SARA-R4/N4 series System Integration Manual [2]. 2.5.3 SPI interface ☞ The SPI interface is not supported by the “00”, “01” and “02” product versions. SARA-R4/N4 series modules include a Serial Peripheral Interface for communications with compatible external device. The SPI interface can be made available as an alternative function, in a mutually exclusive way, over the digital audio interface pins (I2S_WA / SPI_MOSI, I2S_RXD / SPI_MISO, I2S_CLK / SPI_CLK, I2S_TXD / SPI_CS).
SARA-R4/N4 series - Data Sheet UBX-16024152 - R11 Interfaces Page 14 of 41 2.5.4 SDIO interface ☞ The SDIO interface is not supported by the “00”, “01” and “02” product versions. SARA-R4/N4 series modules include a 4-bit Secure Digital Input Output interface (SDIO_D0, SDIO_D1, SDIO_D2, SDIO_D3, SDIO_CLK, and SDIO_CMD) designed to communicate with external compatible SDIO devices. 2.5.5 DDC (I2C) interface ☞ The DDC (I2C) interface is not supported by the “00” and “01” product versions. SARA-R4/N4 series modules include an I2C-bus compatible DDC interface (SDA, SCL) available to communicate with a u-blox GNSS receiver and with external I2C devices as an audio codec: the SARA-R4/N4 series module acts as an I2C master that can communicate with I2C slaves in accordance with the I2C bus specifications [11]. The SDA and SCL pins have internal pull-up to V_INT, so there is no need of additional pull-up resistors on the external application board. 2.6 Audio ☞ Audio is not supported by the “00”, “01” and “02” product versions. SARA-R4/N4 series modules support VoLTE (Voice over LTE Cat M1 radio bearer) for providing audio services. SARA-R4/N4 series modules include an I2S digital audio interface to transfer digital audio data to/from an external compatible audio device. The digital audio interface can be made available as an alternative function, in a mutually exclusive way, over the SPI interface pins (I2S_WA / SPI_MOSI, I2S_RXD / SPI_MISO, I2S_CLK / SPI_CLK, I2S_TXD / SPI_CS).
