This is a simple breakout board for Digi's XTend 900 Modem. This board breaks out all eleven of the pins used by the modem to a 0.1" pitch header. Make sure you connect the XTend modem on the correct side of the board, as indicated by the silkscreen.

This product is only the PCB, no headers will come installed. Soldering a couple 10-pin/2mm XBee headers in will allow you to easily connect and disconnect your XTend modem.
