I want to use two video sources with the lightbridge. HD video from a GoPro and Analogue video (AV) from thermal camera. In order to do that the HD video must connect to the gimbal port. On the lightbridge gimbal port (air module) there are three pins for the HD video: G V+ V-. How can I connect the gopro to these pins in order to get the video. (Not using Zenmuse HD gimbal)
