Assembly instruction:

Just print and assemble as per pictures. Use OUT+ and OUT- on the PCB side of the charging board to solder the Dupont connector. When powered up set once the output voltage with the spindle trimmer. As it is a tester only I set mine to 5V. Do not forget this step as the delivery setting will burn most servos!
