The WF111 and WF121 from Silicon Labs provide 802.11b/g/n connectivity for applications. The WF111 is a simple low-cost solution designed for battery-powered applications and other devices that run an operating system and TCP/IP stack on-board, but still can use the benefits of a module with tightly-integrated electronics, certifications, and simple design in capability. Drivers are available for Linux and Android operating systems. The WF121 is a stand-alone Wi-Fi module providing a fully-integrated 802.11b/g/n radio, TCP/IP stack, and 32-bit MCU platform for embedded applications.
