Sparkfun Electronics Xbee Arduino Shield

The Xbee Arduino Shield is an awesome way to add wireless capability to your Arduino project. The shield form-factor mates directly with any dev board that has an Arduino standard footprint and equips it with wireless communication capabilities using the popular XBee module. This unit works with all XBee modules including the Series 1 and 2, standard and Pro versions. The serial pins (DIN and DOUT) of the XBee are connected through an SPDT switch, which allows you to select a connection to either the UART pins (D0, D1) or any digital pins on the Arduino (D2 and D3 default). Power is taken from the 5V pin of the Arduino and regulated on-board to 3.3VDC before being supplied to the XBee.
