1.1 GainSpan GS2200M Ultra-Low Power 802.11b/g/n Module
The GS2200M module provides a quick, easy, and cost effective way for IoT device
manufacturers to create WiFi connected products. The module provides a built-in
application CPU to run the device's application firmware on the module, eliminating the
need for an external host MCU. Alternatively, the module may be interfaced with a host
MCU via a UART, SPI or SDIO interface.
The GS2200M module supports ultra-low power mode enabling designs for both battery
powered or line powered applications. Alternatively, it can be run self-contained without a
host (to develop a hostless application an SDK is required). The GS2200M is an ideal
solution for organizations with limited WiFi 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 incorporates a full WiFi and TCP/IP networking stack, a full suite of
networking services, including WiFi provisioning, DHCP, TLS/SSL, HTTP(S), mDNS,
DNS, CoAP, XML, JSON and over-the-air firmware upgrade.
The GainSpan 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 WiFi. Applications include smart energy, healthcare and fitness, industrial
controls, commercial building automation, and consumer electronics.
The GainSpan GS2200M module is designed to support the following features:
– An on-board antenna or u.FL connector to add an external antenna for extended
range
– Full Wireless LAN and Network services offload solution minimizes load on host
processor
– Ultra low power consumption through dynamic management modes: Standby,
Sleep, Deep Sleep
– Easy provisioning with Limited AP or WiFi protected set up (WPS 2.0)
– IEEE 802.11 b/g/n connectivity
– UART, SPI, SDIO interface to peripherals or a host MCU
– Security: 802.11i, WPA/2-Personal and Enterprise, legacy WEP, TLS
