Here is a tiny new circuit board for testing OpenROV 2.6 controller boards. Most people won't need it, but the controller board design files are up so this should be up with them! It has an I2C ADC that we use to measure the 3.3V, 5V, and battery power supplies after the board is manufactured. The first board has been assembled but I haven't tested it yet, have to wait for a few parts that aren't in the office now. The board plugs into J1.
