WGM160 Series 1 Wi-Fi Modules
WGM160 devices are secure, low-power, fully certified Wi-Fi modules designed specifically for IoT applications. With a 2.4 GHz 802.11 b/g/n Wi-Fi radio and a 72 MHz Cortex M4 MCU, the device can run the complete Wi-Fi Stack, TCP/IP stack, and your applications. Advanced peripherals like an Ethernet MAC and cap touch allow you to reduce BOM and add features to your products. WGM160 modules are available with or without a built-in antenna (reduces BOM) and an LF XTAL (lower sleep current for Wi-Fi). The earlier version of WGM160P module comes with Gecko OS kernel preloaded in the flash while the new version is without the Gecko OS kernel loaded. Thus, there is no need to remove it before loading a FMAC based application.
