SARA-G3 - Versatile 2.5G GSM/GPRS Cellular Modules

The u-blox SARA-G3 series of 2.5G GSM/GPRS cellular modules features extremely low power consumption and a miniature LGA form factor.

The 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.

Highlights:

  • GSM/GPRS functionality scalable to customer needs
  • Seamless drop‑in migration from SARA‑U UMTS/HSPA modules
  • Smallest footprint; lowest standby current: < 0.90 mA
  • Extended temperature range: -40 to +85°C
  • Simple integration of u‑blox GNSS and A‑GNSS
  • CellLocate®: location based on cellular network

The kits come with a built-in u-blox GPS receiver module, giving designers the flexibility to either test GSM/GPRS functionality alone or to integrate it together with u-blox GPS technology.

For evaluating Assisted-GPS (A-GPS) a u-blox AssistNow A-GPS client is embedded in the firmware stack (EVK-G35 only), providing users with the option of integrating and testing our license-free A-GPS solutions.

EVK-G31 and EVK-G35 evaluation kits include m-center and u-center: u-blox' interactive evaluation tools for configuration, testing, visualization and data analysis of wireless and GPS receivers. These powerful and easy to use tools provide useful assistance during all phases of a system integration project.
