The GS2100M from GainSpan is a compact 802.11 b/g/n module that has been developed for smart energy and sensor applications. The module has 3 high bit-rate sigma delta ADCs for high resolution sensor and measurement devices. It 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 measures 18 mm x 25 mm x 2.5 mm.
