So this works ok grounding to a 12v video TX?

Ground is ground, 0 volts so you're safe

You soldered to the usb plug directly? And tapped into video tx ground wire?

This is a useful mod and it seems to work well. My problem is that having two hoops of wire between the camera and the vTX is not going to be robust in the long term.

However. If the vTX ground is the same as the video ground coming out of the GoPro (I assume it is?) then wouldn't a further improvement be to do the USB ground <-> video ground connection in the gimbal, rather than trail a wire from the moveable camera all the back to the transmitter?

Can anyone tell what the pin out on the ribbon cable is where it joins the USB connector ?

Thanks.
