Micro:Maqueen Plus - an Advanced STEM Education Robot for micro:bit (without micro:bit)

Micro: Maqueen Plus is an advanced version of micro:Maqueen Lite (4.0), which is more powerful and intelligent.Optimized with better power management and larger capacity power supply, it can be perfectly compatible with HuskyLens AI Vision Sensor, which makes it an accessible AI robot teaching tool.

In addition, micro:Maqueen Plus comes with a larger and more stable chassis, more built-in functions and more expansion ports, it is not only suitable for classroom teaching, but also can be suitable for after-school extended exercises and robot competitions.

(Note: micro:bit board is not included.)

What makes micro:Maqueen Plus so powerful?

High Capacity Lithium Battery
• Powered by18650 high capacity lithium battery.
• Onboard charging circuit and battery indicator.

Competition-level Sensors
• 6 line tracking sensors to allow complex routine programs and complicated maze algorithms.
• Supports analog readings and sensor calibrations with only one key.

Rich Extension Interfaces
• 9 GPIO expansion ports, 3 I2C extension ports, 3 servo expansion ports.
• 12 M3 threaded connections.
• Fully compatible with micro: Maqueen Mechanic and HuskyLens AI vision sensor.

High Speed Metal Motor
