I got the APM2.5 board today and currently deciding on exactly how to hook up the crius extend board to the APM2.5 board. Before I start cutting the connector harness, I would like a suggestion on which APM2.5 port should I use to power the extend board, since the GPS port or the 3DR port will provide +5V?
Also, I have an xbee adapter like the one in the picture, should I just use the adapter to connect to the 3DR port instead of combining the two ports into one plug for the extend board?
