Maqueen Lite White micro:bit Educational Programming Robot Platform

The DFRobot Maqueen Lite is a small educational robot for the BBC micro:bit, here with a white protective ABS shell. Motors, wheels, support wheel, shell and battery holder are factory-mounted, only a micro:bit and three AAA batteries are needed. It is programmed graphically with Microsoft MakeCode or with Mind+, which also supports Python. Line following, obstacle detection with ultrasound and infrared remote control work without soldering. The Maqueen 4.2 control core works with micro:bit V1 and V2.

micro:bit and batteries are not included.
