1.1 Product Overview
The GS2101M based modules provide cost effective, low power, and flexible platform to
add WiFi® connectivity for embedded devices for a variety of applications, such as
wireless sensors and thermostats. It uses the GS2000 SoC, which combines ARM® Cortex
M3-based processors with a 802.11b/g/n Radio, MAC, security, & PHY functions, RTC
and SRAM, up to 4 MB FLASH, and on-board and off module certified antenna options.
The module provides a WiFi and regulatory certified IEEE 802.11b/g/n radio with
concurrent network processing services for variety of applications, while leverage existing
802.11 wireless network infrastructures.
