1.1 Overview
SARA-G3 series GSM/GPRS cellular modules and SARA-U2 series GSM/EGPRS/HSPA cellular modules are versatile
solutions offering voice and/or data communication over diverse radio access technologies in the same miniature
SARA LGA form factor (26 x 16 mm) that allows seamless drop-in migration between the two SARA-G3 and
SARA-U2 series and easy migration to u-blox LISA-U series GSM/EGPRS/HSPA+ modules, LISA-C2 series CDMA
modules, TOBY-L1 series LTE modules and to TOBY-L2 series GSM/EGPRS/DC-HSPA+/LTE modules.
SARA-G350 and SARA-G340 are respectively quad-band and dual-band full feature GSM/GPRS cellular modules
with a comprehensive feature set including an extensive set of internet protocols and access to u-blox GNSS
positioning chips and modules, with embedded A-GPS (AssistNow Online and AssistNow Offline) functionality.
SARA-G310 and SARA-G300 are respectively quad-band and dual-band GSM/GPRS cellular modules targeted for
high volume cost sensitive applications, providing GSM/GPRS functionalities with a reduced set of additional
features to minimize the customer’s total cost of ownership. SARA-U2 series include variants supporting band
combination for North America and band combination for Europe, Asia and other countries. For each
combination, a complete UMTS/GSM variant and a cost-saving UMTS-only variant are available. All SARA-U2
series modules provide a rich feature set including an extensive set of internet protocols, dual-stack IPv4 / IPv6
and access to u-blox GNSS positioning chips and modules, with embedded A-GPS (AssistNow Online and
AssistNow Offline) functionality.
Table 1 describes a summary of interfaces and features provided by SARA-G3 and SARA-U2 series modules.
