This board breaks out all 20 pins of the XBee to a 0.1" standard spacing dual row header. The spacing between 0.1" headers is 0.5" making it breadboard DIP friendly. We highly recommend using the female sockets to avoid having to solder the XBee permanently to the breakout board. This is the PCB only. Please order the accompanying 2mm sockets (you'll need 2!) and 0.1" headers below.
