Hello and thank you for your reply, So yes I have the dock but don't want to use the USB micro socket to power the onion. What I want to do is design a board that mounts on the 30 pin expansion socket to give me access to other things like 12c, SPI ect. but also want to have a 24VDC to 5 VDC supply on this board and want to feed the 5VDC into the expansion socket if this is possible?

Powering through the 30pin expansion socket.
Powering the onion through the 30 pin expansion socket. I would like to build a board that will mount on the 30 pin expansion socket and feed the board with 5vdc through the expansion socket is this possible or is it only for feeding external devices.
