GS2100M Low Power
High Speed 802.11b/g/n Module
Smart Energy, Cost and Size Optimized
The GS2100M is a small foot print module that provides a quick,
easy, and cost effective way for manufacturers to add Wi-Fi
connectivity to their products. Intended for smart energy and sensor
applications, the module has 3 high bit-rate sigma-delta ADCs for
high resolution sensor and measurement devices.
This module provides a low cost, high speed serial to Wi-Fi
connection to an embedded design built on an 8/16/32-bit
microcontroller, through an SDIO, SPI or UART interface.
The GS2100M is an ideal solution for organizations with limited Wi-Fi
or RF expertise or for those seeking faster time to market, as it
reduces RF design time and removes the burden of testing and
certification. The module is IEEE 802.11b/g/n compliant, and meets
worldwide regulatory and Wi-Fi Alliance certification requirements.
The module runs the full Wi-Fi and TCP/IP networking stacks,
completely offloading the host microcontroller. It supports a complete
suite of security protocols, also without tasking the host
microcontroller, including WPA/WPA2-Enteprise and Personal
security modes, legacy WEP encryption, and upper layer security
protocols such as TLS/SS and HTTPs. Alternatively, it can be run
self-contained without a host.
For ease of provisioning, the module can be set up simply and easily
from a smartphone or laptop through the innovative Limited AP mode
or with Wi-Fi Protected Setup (WPS).
The module is single sided with castellation on the edges for the I/O
connections for soldering down on the product’s baseboard.
It is available with an u.FL connector to add an external antenna for
max performance or a PCB antenna for convenience while saving
space. It is US/Canada (FCC /IC), Europe (CE/ETSI, Japan (TELEC),
and Wi-Fi certified.
