Product Description
The GS2101M module series provides a quick, easy, and
cost effective way for device and appliance manufacturers
to add Wi-Fi connectivity to their products. The module
runs the SEP 2.0 Smart Energy Profile stack and has 3 high
bit-rate sigma-delta ADCs for high resolution sensor and
measurement devices, making it ideally suited for smart
energy and sensor applications.
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, over SDIO interfaces.
The GS2101M 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.
The GS2101M has extended range with industry leading
receiver sensitivity. It is available with an U.FL (Universal
change) 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)
and Japan (TELEC) certified.
The GS2101M module is easily designed into embedded
systems, allowing customers to develop a broad array of
devices and appliances that connect to other local devices
or the Internet over Wi-Fi. Applications include smart
energy, smart home, healthcare and fitness, industrial
controls, commercial building automation, and consumer
electronics.
