Shields – WiFly Shield

Finally, we have wi-fi to an Arduino!

The WiFly Shield equips your Arduino the ability to connect to 802.11b/g wireless networks. Power is taken from the Vin pin of your Arduino, regulated to 3.3V. You’ll communicate with the WiFly Shield over SPI using Arduino digital pins 10-13 (CS, MOSI, MISO, SCLK respectively).
