Micro:Maqueen Plus V2 - an Advanced STEM Education Robot for micro:bit (without micro:bit)

I'm Maqueen Plus V2, the latest version of the STEAM educational robot Maqueen Plus. Optimized with more expansion ports, larger capacity power supply, and larger body, I can be perfectly compatible with more peripheral components like HuskyLens AI camera and Maqueen Mechanic kits, which makes me an accessible STEAM robot teaching tool for primary and secondary students. I'm not only suitable for classroom teaching, but also can be used for after-school extended exercises and robot competitions.
Besides all the functions of Maqueen Lite, I offer richer and more flexible functions and stronger performance. Whether you have ever used Maqueen series products or not, you'll find it very easy to get started.

What’s new in Maqueen Plus V2?
1. Two versions to choose from: 4 AA battery and 18650 battery
2. New plastic box with a deeper base, enough room for the assembled car
3. Frosted acrylic protective plate at the bottom, more durable and reliable
4. The number of Line-tracking sensors has changed from 6 to 5, more convenient to program and optimize line-tracking codes
5. Employs the motors whose parameters are the same as previous Maqueen, running steadily and smoothly
6. Changes ultrasonic sensor to SR04, easier to install
7. Add 4 RGB ambient lights at the base, RGB car lights have been changed to LEDs
8. Delete the less usable magnetic encoder
