Has anyone added any sensors or other devices to their GalaxyRVR? As far as I can tell pins A0, A1, and A2 look like they might be pulled out to the shield. There doesn’t seem to be much in the way of expansion possible. That said, has anyone swapped the UNO for a MEGA instead so that the additional pins are available?
Yes, the UNO pins A0, A1, and A2 are extended to the Mars rover expansion board. The interfaces on the Mars rover expansion board are mostly occupied, so it’s not convenient to add other sensors. We haven’t tried replacing the UNO with a MEGA.
