Wireless LAN (WLAN) SPI Module OWL253

Key features 

The Wireless LAN Module OWL253 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 interface between the TCP/IP stack in the device and in 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, WinCE and embedded systems and may be adapted for any microcontroller.
