This is a simple breakout board for the popular XBee product from Maxstream.
Because the XBee modules use tighter 2mm pin spacing, you can't plug them into regular breadboards. This board breaks out all 20 pins of the XBee to a 0.1" standard spacing dual row header.
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 for plugging it into the breadboard..
