1.1 Overview
The SARA-R4 series comprises LTE Cat M1 modules supporting data transmission in the miniature SARA LGA
form-factor (26.0 x 16.0 mm, 96-pin), that allows an easy integration in compact designs and a seamless drop-in
migration from u-blox cellular module families.
SARA-R4 series modules are form-factor compatible with u-blox LISA, LARA and TOBY cellular module families
and are pin-to-pin compatible with u-blox SARA-N, SARA-G and SARA-U cellular module families. This facilitates
migration from the u-blox NB-IoT, GSM/GPRS, CDMA, UMTS/HSPA and other LTE modules, maximizes customers
investments, simplifies logistics, and enables very short time-to-market.
The modules are ideal for LPWA applications with low to medium data throughput rates, as well as devices that
require long battery lifetimes, such as connected health, smart metering, smart cities and wearables.
SARA-R4 series includes the following modules:
SARA-R404M single-band modules designed primarily to operate in North America on Verizon network
SARA-R410M-01B quad-band modules designed primarily to operate in North America on AT&T network
LTE Cat M1 supports vehicular handover capability and delivers the technology necessary to enable the use of
the modules in applications such as vehicle, asset and people tracking where mobility is a pre-requisite. Other
applications where the module is well suited include and are not limited to: smart home, security systems,
industrial monitoring and control.
SARA-R4 series modules support data communication with a throughput of 375 kb/s.
