Versatile 2.5G GSM/GPRS modules

SARA-G3 series Versatile 2.5G GSM/GPRS modulesThe SARA-G3 series of GSM/GPRS modules feature extremely low power consumption and a miniature LGA form factor. SARA-G3 modules are interchangeable, and have been designed with the diverse needs of M2M customers in mind. Different functionalities and feature sets are available to meet different customer and application requirements. SARA-G350 and SARA-G340 are full-feature GSM/GPRS modules with a comprehensive feature set, including an extensive set of internet protocols (TCP, UDP, HTTP and FTP). They have fully integrated access to u-blox GNSS positioning chips and modules, along with embedded A-GNSS (AssistNow Online and AssistNow Offline) functionality.

SARA-G350 is the quad-band version for global connectivity and SARA-G340 (900/1800 MHz) is the dual-band version for cost optimized use in Europe and Asia. Their rich feature set enables customers to easily develop a wide range of M2M devices with minimum software development on the host processor.

SARA-G300/G310 modules target high volume, cost sensitive applications, and provide “bit pipe” GSM/GPRS functionalities while minimizing the customer’s total cost of ownership. Functionalities requiring dedicated and expensive hardware components are eliminated where they are not needed or can be implemented in the host processor.

The SARA-G350 ATEX is an ATEX / IECEx certified variant that further complements the product family by offering the ideal solution for the development of smart devices deployed in potentially explosive environments.
