SARA-U2 series - Data Sheet
1 Functional description
1.1 Overview
The SARA-U2 series modules are a 3.75G UMTS/HSPA solution in the miniature (26.0 x 16.0 mm) SARA LGA
form factor that allows seamless drop-in migration from u-blox SARA-G3 series GSM/GPRS modules and easy
migration to u-blox LISA-U series UMTS/HSPA+ modules, u-blox LISA-C2 series CDMA modules and to u-blox
TOBY-L series LTE modules. SARA-U2 modules feature HSPA data-rates of 7.2 Mb/s (downlink) and 5.76 Mb/s
(uplink). The modules offer data and voice communication over an extended operating temperature range of –
40 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 North America
operation and for operation in Europe, Asia and other countries. 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.
