Arduino fans can now take their hacking projects to a new level with the release by the Arduino crew of their WiFi shield. The shield is designed around an Atmega 32UC3 32bit microcontroller which controls the WiFi stack and the HDG104 from H&D Wireless. The Arduino communicates over SPI with the Atmega32. They use an open source version of TCP/IP and the WiFi software stack allowing for greater user control and maximum hackability.
The shield supports 802.11 b/g network along with WEP and WPA2 Personal security modes.
Links to the board files and Arduino WiFi library can be found on the WiFi shield product page.
The WiFi shield is available from the Arduino store.
