SARA-U2 series - Data Sheet
1 Functional description
1.1 Overview
The SARA-U2 series modules are a 3.75G UMTS/HSPA solution with GSM/(E)GPRS fall-back in the miniature
(26.0 x 16.0 mm, 96-pin) SARA LGA form factor that allows seamless drop-in migration from / to other u-blox
cellular modules families.
SARA-U2 modules feature HSPA data-rates of 7.2 Mbit/s (downlink) and 5.76 Mbit/s (uplink). The modules offer
data and voice communication over an extended operating temperature range of –40 °C to +85 °C, with low
power consumption and a rich feature set including dual-stack IPv4 / IPv6.
The SARA-U2 series includes variants supporting band combinations for worldwide operation, for operation in
North America, Europe, Asia and other countries. A cost-saving UMTS-only variant is also available.
SARA-U2 modules are complete, fully qualified and certified solutions, which reduce costs and enable short time
to market. They are ideally suited to M2M applications such as: mobile internet terminals, car infotainment and
telematics, Automatic Meter Reading (AMR), Remote Monitoring Automation and Control (RMAC), surveillance
and security, road pricing, asset tracking, fleet management, anti-theft systems, and Point of Sales (PoS)
terminals. SARA-U2 modules support full access to u-blox GNSS receivers via serial port. Thus any host processor
connected to the cellular module through a single serial port can control both the cellular module and the
positioning chip/module. The compact SARA 26.0 x 16.0 mm form factor with LGA pads (functionally referred to
as “pins”) allows fully automated assembly with standard pick & place and reflow soldering equipment for cost-
efficient, high-volume production.

SARA-U201 ATEX and SARA-U270 ATEX modules provide the same feature set as the SARA-U201 and SARA-U270 modules respectively,
with the additional certification for use in potentially explosive atmospheres. Unless otherwise specified, SARA-U201 refers to all
SARA-U201 ATEX and SARA-U201 modules; in the same way SARA-U270 refers to both SARA-U270 ATEX and SARA-U270 modules.
