Hi Matt,
I just looked at the 3DR GPS/MAG module schematics shown on their website and here it is:
1. 3DR GPS cable:
pin1 = +5V -> connect to X2 GPS port USART4 +5V;
pin2 = RxD -> connect to U4TxD;
pin3 = TxD -> connect to U4RxD
pin4 = not used
pin5 = not used
pin6 = GND
2. MAG cable:
pin1 = not connected
pin2 = SCL -> connect to I2SCL
pin3 = SDA -> connect to I2SDA
pin4 = GND
3. Telemetry - widely explained by Kai ( gervais ) in the first post - http://fs1.directupload.net/images/141121/yoz2g6ww.png
URGENT! PLEASE DO READ MANUALS AND GERVAIS EXPLANATIONS....PLEASE DO!
