Wifi Shield

This Wifi Shield utilizes a RN171 wifi module to provide your Arduino/Seeeduino with serial Ethernet's function. It only takes two pins to hook your device up to 802.11b/g wireless networks with this shield. It features an independent antenna which can cover a wider range and transmit stronger signals. With supports for common TCP, UDP and FTP communication protocols, this Wifi Shield can meet needs of most wireless network projects, like smart home networks, robot controls or personal weather stations,etc. We prepared an easy and convenient command set for this shield so that you can use neat and concise code to run the function.
