iPhone dock connector powering peripheral
I am trying to connect to the iPhone dock serial port with a microcontroller, but I would also like to power from the iPhone. I got the +3.3v, Tx, Rx and serial gnd pins off of the iPod linux wiki, but I don't know which pin I should be using for power gnd. Can anyone here help?
