I built my ROV about 6 yrs ago it runs off of a rc radio and a receiver in the Hull of the ROV.
I have finally come across an OSD that has a magnetometer in it so I now have internal compass but I still would like to come up with a way to have a depth reading.
I don’t have an on board computer of any type (except I guess the new OSD Chip) nor do I have any knowledge of how to use them, I wouldn’t even know where to begin
I was hoping maybe some one here had tackled this before, everything was run on Arduino or what ever it is the Blue Rov runs on.
Sorry its kind of vague but I really am old school
