1 Functional description
1.1 Overview
SARA-R4 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 series modules provide software-based multi-band configurability enabling international
multi-regional coverage in LTE Cat M1 / NB1 and (E)GPRS radio access technologies.
SARA-R4 series modules offer data communications up to 375 kb/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 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. The
flexibility extends further through mode selection as M1-only/preferred or NB1-only/preferred.

Feature
Description
GNSS via modem 15
Full access to u-blox positioning chips and modules is available through DDC (I2C) interface.
This means that from any host processor, a single serial port can control the SARA-R4 series
cellular module and the u-blox positioning chip or module.
CellLocate 16
Enables the estimation of device position based on the parameters of the mobile network cells
visible to the specific device based on the CellLocate® database. CellLocate® is available via a set
of AT commands for CellLocate® service configuration and position request.
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 17
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 (CE) Mode A, introduced in 3GPP Rel.13, is used to improve cell signal
penetration.
Coverage Enhancements
Mode B 18
Coverage Enhancements (CE) Mode B, introduced in 3GPP Rel.13, is used to further improve cell
signal penetration.
Connected Mode Mobility 19
LTE Cat M1 Connected Mode Mobility (CMM) with CE Mode A
Release Assistance
Indicator 19
The 3GPP Release Assistance feature allows the module to request for the RRC connection to be
dropped as soon as the message has been received by the network. This feature allows a
reduction in the module power consumption.
LwM2M with dynamically
loaded objects 16
Method allowing dynamically loaded run time objects for customers to configure u-blox modules
to define necessary objects, create instances of those objects as appropriate, manage module
LwM2M protocol stack to interact with the LwM2M server.
Backup and restore 20
This feature allows the modules to autonomously restore the flash file system using the last
backup stored on the module itself. For further details about the backup and restore feature see
the +UBKUPDATA AT command description in the SARA-R4 series AT commands manual [1],
and the backup and restore technical note [5].
Table 3: Some of the main features supported by SARA-R4 series modules
u-blox is extremely mindful of user privacy. When a position is sent to the CellLocate® server,
u-blox is unable to track the SIM used or the specific device.

2 Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
SARA-R4 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-M, NB-IoT and the 2G radio access technologies (described in
the SARA-R4 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 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 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 series system integration
manual [2] and the SARA-R4 series AT commands manual [1]).
2.3 System functions
2.3.1 Module power-on
SARA-R4 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.

UBX-16024152 - R23 Interfaces Page 12 of 43
C1-Public
2.3.2 Module power-off
SARA-R4 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 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 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 series modules can be reset (re-booted) by:
AT+CFUN command (see the SARA-R4 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 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 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 series system
integration manual [2] and the SARA-R4 series AT commands manual [1].
2.5 Serial communication
The SARA-R4 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
for multiplexer control for all AT commands, and noniDial Up Network (noniDUN) data connections. UDP, TCP for Dial Up Network (DUN) data connection. It requiresthe host to have and use its own for uiblox GNSS data tunneling (not supported by the “008" and “01 B" versions).
SARA-R4 series - Data sheet
UBX-16024152 - R23 Interfaces Page 13 of 43
C1-Public
2.5.1 UART interface
SARA-R4 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 ITU-T V.24 recommendation [11],
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 b/s
The default frame format is 8N1 (8 data bits, no parity, 1 stop bit)
Hardware flow control is not supported by the00B”, “01B” 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 00B” and “01B” product versions.
The UART serial interface can be conveniently configured through AT commands. For more details,
see the SARA-R4 series AT commands manual [1] and the SARA-R4 series system integration
manual [2].
2.5.1.1 Multiplexer protocol
SARA-R4 series modules include multiplexer functionality as per 3GPP TS 27.010 [8] 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).
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 00Band “01Bversions).
2.5.2 USB interface
SARA-R4 series modules include a high-speed USB 2.0 compliant interface with a maximum 480 Mb/s
data rate according to the USB 2.0 specification [12] 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 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.

UBX-16024152 - R23 Interfaces Page 14 of 43
C1-Public
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 voltage (5.0 V typical).
The USB interface is available as an AT command / data communication interface only if an
external valid USB VBUS 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 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 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 series system
integration manual [2].
2.5.3 SPI interface
The SPI interface is not supported by the “00B”, “01B, “02B”, “52B”, “63B”, “73B, 83Bversions.
SARA-R4 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).
2.5.4 SDIO interface
The SDIO interface is not supported by “00B”, “01B”, “02B”, “52B”, “63B”, “73B”, “83B” versions.
SARA-R4 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 “00B” and “01B” product versions.
SARA-R4 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 for example an audio
codec: the SARA-R4 series module acts as an I2C host that can communicate with I2C devices in
accordance with the I2C-bus specifications [13].
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 “00B”, “01B”, “02B”, “52B”, “63B”, “73B” and “83B” versions.
SARA-R4 series modules support VoLTE (Voice over LTE Cat M1 radio bearer) for providing audio
services.
SARA-R4 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).
2.7 GPIO
SARA-R4 series modules include pins that can be configured as general purpose input/output or to
provide custom functions as summarized in Table 4 (for further details, see the SARA-R4 series
system integration manual [2] and the SARA-R4 series AT commands manual [1]).

4 Electrical specifications
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating
section may cause permanent damage. These are stress ratings only. Operating the module at
these or at any conditions other than those specified in the Operating Conditions sections (section
4.2) of the specification should be avoided. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.
Operating condition ranges define limits within which the functionality of the device is guaranteed.
Electrical characteristics are defined according to the verification on a representative number of
samples or according to the simulation.
Where application information is given, it is advisory only and is not part of the specification.

4.3 Parameters for ATEX applications
This section provides useful parameters and information to integrate SARA-R4 series modules in
applications intended for use in areas with potentially explosive atmospheres (ATEX), describing:
Total internal capacitance and inductance of the modules (see Table 25)
Maximum RF output power at the antenna (ANT) pin of the modules (see Table 26)
Any specific applicable requirement for the implementation of the apparatus integrating the
SARA-R4 series modules, intended for use in potentially explosive atmospheres, must be fulfilled
according to the exact applicable standards: check the detailed requisites on the pertinent
normative for the application, as for example the IEC 60079-0 [14], IEC 60079-11 [15], and
IEC 60079-26 [16] standards.
The certification of the application device that integrates a SARA-R4 series module and the
compliance of the application device with all the applicable certification schemes, directives and
standards required for use in potentially explosive atmospheres are the sole responsibility of the
application device manufacturer.
Table 25 describes the maximum total internal capacitance and the maximum total internal
inductance, considering internal parts tolerance, of the SARA-R4 series modules.

7.2 Moisture Sensitivity Levels
SARA-R4 series modules are Moisture Sensitive Devices (MSD) in accordance to the IPC/JEDEC
specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required.
SARA-R4 series modules are rated at MSL level 4. For more information regarding moisture
sensitivity levels, labeling, storage and drying, see the u-blox package information user guide [3].
For the MSL standard, see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).
7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see the SARA-R4 series
system integration manual [2]).
Failure to observe these recommendations can result in severe damage to the device!
7.4 ESD precautions
SARA-R4 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling SARA-R4 series modules without proper ESD protection may
destroy or damage them permanently.
SARA-R4 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD
precautions typically applied to ESD sensitive components.
Table 7 details the maximum ESD ratings of the SARA-R4 series modules.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling
and operation of any application that incorporates the SARA-R4 series module.
ESD precautions should be implemented on the application board where the module is mounted, as
described in the SARA-R4 series system integration manual [2].
Failure to observe these recommendations can result in severe damage to the device!
