Multi Expansion Board for UNIHIKER M10/K10 and micro:bit

The DFRobot expansion board for UNIHIKER K10, UNIHIKER M10 and micro:bit adds more connections, a battery power supply and motor drivers. It drives up to four DC motors and six servos; the servos are powered directly from the battery and therefore do not load the controller. A holder for an 18650 battery with charge and discharge circuit makes cable-free robots possible. The 18650 battery is not included.
