The WiFly Shield equips your Arduino microcontroller board with the ability to connect to 802.11b/g wireless networks. The featured components of the shield are a Roving Network's RN-131C wireless module and an SC16IS750 SPI-to-UART chip. The SPI-to-UART bridge is used to allow for faster transmission speed and to free up the Arduino's UART.
This updated version of the WiFly Shield breaks out the PI09, FORCE WAKE, and hardware reset lines. It also has a faster crystal (14.7456MHz) and uses the RN-131C chip.
Power is taken from the Vin pin of your Arduino, regulated to 3.3V, and provided to both the RN-131G and the SC16IS750. You'll communicate with the WiFly Shield over SPI using Arduino digital pins 10-13 (CS, MOSI, MISO, SCLK respectively).
The shield includes the RN-131C, SC16IS750 and their supporting components. The shield also provides a small prototyping area, with 0.1" spaced holes. Headers are not included; see options below for headers you can solder on.
