While looking for small compatible boards I have seen there was this AIO board, I didn’t think there was another micro AIO board supported by Ardupilot and that this one had changed the gyro, but the supported version is still available in places, unfortunately it’s expensive but it’s the only one I could find with an analogue OSD.
I keep looking at that HD zero camera, if I can hit over an hour with the analogue camera then il get it to try and make a digital version
I made a 3d centre to glue in rather than carbon plate, I can get it down to just over 1g with the fc mount integrated.
