I have a Diatone GT m3 which has TBS Unify VTX and I have a simple mic which I just want to connect in to the audio input on the Unify so my videos have some sound in. I'm not trying to use smartAudio or anything clever, but despite checking the user guide, I cannot figure out where I would solder on to. It might be that Diatone have connected the audio input on the TBS board to the Fury F4 flight controller and I need to solder on to there. Can anyone point me in the right direction? Thanks!
