Key features
The Wireless LAN SDIO Module 222a has been developed for integration in industrial, medical, and other demanding devices providing state of the art low power features and dual-band support for both 2.4GHz and 5GHz radio bands. The accompanying software driver works as the interface between the TCP/IP stack in the device and the module. The module minimizes the work needed to implement Wireless LAN (IEEE 802.11a/b/g/n) in a device as it provides all hardware, type approval, EMC certification etc. It is developed for reliable, high demanding devices and applications. The driver is available for Linux and WinCE, and may be adapted for any micro controller.
