Maqueen micro:bit Plus V3 AA Battery Educational Programming Robot Platform

The DFRobot Maqueen Plus V3 is a versatile learning robot for education and robotics competitions. The AA version is distinguished by the included Battery Board for four AA batteries, which allows flexible operation without a lithium battery. All other functions such as the precise line-tracking system with five sensors, the matrix laser distance sensor with up to 60 Hz measurement rate, and the powerful metal motors with PID encoder control are retained. This version is also modular and offers numerous expansion options via GPIO and servo ports. RGB headlights, ambient lighting, and buzzer make the robot interactive and ideal for creative STEM projects. This makes the AA version particularly suitable for users who rely on easily available batteries and prefer uncomplicated power supply.
