DIY GoPro3 video out cable
Make your own videocable for FPV, an article from rcexplorer.se: directlinkGopro removed the 2.5mm video out jack. But fear not, the GoPro 3 is still able to output the composite video we need for FPV flying. Instead of a normal 5 pin mini USB connector, GoPro chose the much less common 10 pin version. This connector now contains the standard USB pins as well as microphone input and the video output.
