Purchased recently the BluROV2, during assembly, it mentions that the yellow lumen controller cable should be plugged into channel 7 of the Pixhawk, but in the current pre-assembled configuration, channel 7 its already busy with something else, so I wonder if I am missing something?
Channel 7 looks clear. If you look closely, there’s a bit of a gap. You will just need to nudge the other connectors apart a bit and slide the Lumen signal wire into Channel 7. Its a tight fit and definitely not ideal.
