Xbee pins Cerbuino bee

How can I send power to the pins that are made for the Xbee? Is there an easy way to do it, or do I need to get into hackery and rlp to do it? I think it would be interesting, if I ever need it, to put a not-xbee in there and have it do stuff, like a custom made board

not sure what you are asking. the board provides power to the xbee headers.

no, like send data though through the pins meant to send and receive data from the Xbee

The interface to the Xbee socket is serial port COM1.
