Functional description
1.1 Overview
The SARA-R4 series modules are a multi-band LTE-M / NB-IoT / 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-M / NB-IoT and (E)GPRS radio access technologies.
SARA-R4 series modules offer data communications 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 NB-IoT).
SARA-R4 series modules are form-factor compatible with the u-blox LISA, LARA and TOBY cellular
module families and are pin-to-pin compatible with the u-blox SARA-N, SARA-G and SARA-U cellular
module families. This facilitates migration from other u-blox LPWA, GSM/GPRS, CDMA, UMTS/HSPA
and higher LTE categories modules, maximizing customer investments, simplifying logistics, and
enabling very short time-to-market.
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.
Furthermore, the SARA-R42 series, including the SARA-R422, SARA-R422S, SARA-R422M8S and
SARA-R422M10S modules support a comprehensive set of 3GPP Rel. 14 features for LTE Cat M1 and
Cat NB2 that are relevant for IoT applications.
SARA-R422M8S is pre-integrated with the u-blox M8 GNSS receiver chip and SARA-R422M10S is
pre-integrated with the u-blox M10 GNSS receiver chip. They both include a separate GNSS antenna
interface, which provides highly reliable and accurate positioning data simultaneously with LTE
communication. In addition, the module offers unique hybrid positioning, in which the GNSS position
is enhanced with u-blox CellLocate® data, providing location always and everywhere.
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.
SARA-R4 modules leverage hardware-based security functions provisioned in a secured production
environment, to ensure that the module only runs authorized firmware.

Feature
Description
Firmware update
Over The Air (uFOTA)
u-blox firmware module update over the LTE air interface client/server solution using LwM2M.
Integrated GNSS receiver 14 SARA-R422M8S and SARA-R422M10S modules are pre-integrated with a u-blox M8 and M10
GNSS receiver respectively, comprehensive of a dedicated GNSS antenna interface, LNA and SAW
filter for a highly reliable, accurate positioning data.
The GNSS system is totally independent from the LTE system and can run concurrently to a LTE
communication.
External GNSS access and
control via modem 15
Access to external u-blox positioning chips and modules is available through I2C interface.
This means that from any host processor, a single serial port can control the SARA-R4 series
cellular module and the separated 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 20
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 21
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 related section in the application development guide [4][5].
Antenna dynamic tuning 22
Control of an external antenna tuning IC via two 1.8 V digital pins that change dynamically their
high/low state in real time according to the cellular band used by the module.
Table 3: Main features of SARA-R4 series modules

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, SARA-R422, SARA-R422S, SARA-R422M8S, and SARA-R422M10S modules, which
support 2G radio access technology, 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 the SARA-R410M 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 13).
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
Cellular antenna RF interface (ANT)
The ANT pin is the cellular RF antenna I/O interface, designed with 50 characteristic impedance.
2.2.2
☞
GNSS antenna RF interface (ANT_GNSS)
The GNSS antenna RF interface is not supported by SARA-R410M, SARA-R412M, SARA-R422, or
SARA-R422S modules.
The ANT_GNSS pin represents the GNSS RF input of the SARA-R422M8S and SARA-R422M10S
modules, designed with 50 characteristic impedance and with an internal DC block, suitable for both
active and/or passive GNSS antennas due to the built-in SAW filter followed by an LNA in front of the
integrated high performing u-blox M8 or u-blox M10 concurrent positioning engine.
2.2.3
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 modules can be properly switched on by:
•
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, 4.2.9).
The PWR_ON line has to be driven by open drain, open collector or contact switch.
•
Low level on the PWR_CTRL 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,
4.2.10). The PWR_CTRL line has to be driven by open drain, open collector or contact switch.
2.3.2
Module power-off
SARA-R4 series modules can be properly switched off, with storage of the current parameter settings
in the module’s internal non-volatile memory 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 4.2.9)
Low pulse on the PWR_CTRL pin for a valid time period (see section 4.2.10)
A faster and safe power-off procedure of the specific SARA-R422, SARA-R422S, SARA-R422M8S
and SARA-R422M10S modules, with storage of the current parameter settings in the module’s
internal non-volatile memory and without proper network detach, can be triggered by:
•
•
AT+CFUN=10 command (see the SARA-R4 series AT commands manual [1])
Toggling the GPIO input pin configured with the fast and safe power-off function (see section 2.7)
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
Low level on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time
period (see 4.2.11). RESET_N line has to be driven by open drain, open collector or contact switch.
SARA-R4 series modules automatically switch off, with storage of the current parameter settings in
the module’s internal non-volatile memory and a clean network detach, after having sent the last
gasp, once the feature is enabled and triggered (see the SARA-R4 series AT commands manual [1],
+ULGASP AT command).
2.3.3
Module reset
SARA-R4 series modules can be reset (re-booted) by:
•
AT+CFUN=15 command (see the SARA-R4 series AT commands manual [1] for detailed options).
This causes an “internal” or “software” reset of the module. The current parameter settings are
saved in the module’s internal non-volatile memory and a clean network detach is performed.
An abrupt emergency reset (reboot) is triggered on the SARA-R422, SARA-R422S, SARA-R422M8S
and SARA-R422M10S modules, without storage of current parameter settings and without a clean
network detach, when:
•
a low level is applied on the PWR_CTRL pin for a valid time period (see section 4.2.10)

2.4 SIM
2.4.1
SIM interface
SARA-R4 series modules provide a SIM interface on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins to
connect an external SIM card or UICC chip.
SARA-R410M and SARA-R412M modules support both 1.8 V and 3.0 V types of SIM / UICC, with
automatic voltage switch implemented according to related specifications.
SARA-R422, SARA-R422S, SARA-R422M8S, and SARA-R422M10S modules only support the 1.8 V
type of SIM / UICC.
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].

2.5.1.1
Multiplexer protocol
SARA-R4 series modules include multiplexer functionality as per 3GPP TS 27.010 [8] on the primary
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 simultaneous sessions over the
primary UART physical link. 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 SARA-R410M-01B or
SARA-R422-00B product versions).
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]. 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 the SARA-R410M
and SARA-R412M modules and an external host processor, available for AT and data communication,
FW upgrade by means of the FOAT feature.
The USB is the interface of SARA-R4 series modules available for FW upgrade by means of the u-blox
EasyFlash tool and for diagnostic purposes.
SARA-R410M and SARA-R412M modules provide the following USB lines:
•
•
the USB_D+ / USB_D- lines, carrying the USB data and signaling
the VUSB_DET input pin to enable the USB interface by applying an external voltage (5.0 V typical)
SARA-R422, SARA-R422S, SARA-R422M8S, and SARA-R422M10S provide the following USB lines:

Page 18 of 51
SARA-R4 series - Data sheet
☞
The USB interface is available as an AT / data communication interface on the SARA-R410M and
SARA-R412M modules 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.
☞
AT commands and data communication are not supported via USB interface on SARA-R422,
SARA-R422S, SARA-R422M8S, or SARA-R422M10S: the USB interface is available on these
modules only for FW upgrade by means of the u-blox EasyFlash tool and for diagnostic purposes.
☞
If the USB interface is enabled, the module does not enter the low power deep sleep mode: the
external voltage needs to be removed from the VUSB_DET / USB_5V0 and USB_3V3 input pins of
the module to let it enter the Power Saving Mode defined in 3GPP Rel.13.
☞
It is highly recommended to provide access to the V_INT, PWR_ON / PWR_CTRL, VUSB_DET /
USB_5V0, USB_3V3, USB_D+, USB_D-, RSVD #33 pins for FW update and for diagnostic purpose,
by means of test points directly connected to the pins, or by dedicated connector / circuit.

(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 SARA-R410M-01B product versions.
SARA-R4 series modules include an I2C-bus compatible DDC interface (SDA, SCL) available to
communicate with an external u-blox GNSS receiver27 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 local
devices in accordance with the I2C-bus specifications [13].
27
Dedicated AT commands for the integration with external u-blox GNSS receiver are not supported by SARA-R410M-01B,

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 31)
Maximum RF output power at the antenna (ANT) pin of the modules (see Table 32)
☞
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 31 describes the maximum total internal capacitance and the maximum total internal
inductance, considering internal parts tolerance, of the SARA-R4 series modules.
