GainSpan Releases Wi-Fi Mini-module for the IoT

GS2200GainSpan has introduced a new ultra-low power Wi-Fi module for IOT Applications that is the size of a penny. The GS2200MIZ Minimodule provides a low-cost, convenient way for developers to add connectivity to their smart products, from commercial and industrial devices to smart home and audio/video applications, such as battery-powered cameras and security systems, all in a very compact size.

The GS2200M has a powerful feature set including AP and Station concurrent mode operation, a comprehensive set of provisioning methods and security protocols (WPA2 Enterprise, RSA 4K, AES256, SSL/TLS 1.2), and a 260nA hibernate mode. It also supports such protocols as embedded DHCP, DNS clients and servers, XML parser, and Bonjour service and device discovery.

These fully certified modules are based on the GainSpan GS2000 dual mode Wi-Fi (802.11b/g/n) and 802.15.4 SoC, and provide a variety of features requested by customers for IoT devices such as low-power consumption, high security through on-chip hardware crypto block, Wi-Fi direct and concurrent mode, where the device can act as a station and an access point concurrently.

The GS2200M can be used in a hostless mode (no external MCU) or hosted mode where it connects to an 8/16/32-bit microcontroller using UART/SPI, or SDIO interfaces.
