Waveshare AlphaBot2 Robot Building Kit for BBC micro:bit (no micro:bit)

Overview
This AlphaBot2 robot kit is designed to use with the BBC micro:bit (not included). It features rich common robot functions including line tracking, obstacle avoiding, ultrasonic ranging, Bluetooth/2.4G remote control, etc.

Thanks to the highly integrated modular design, it is fairly easy to assemble by a snap, no soldering, no wiring. After a few minutes spent on hardware assembing, you're almost there, our open source demo codes is ready to help you get started fast.

AlphaBot2 Features
AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.

AlphaBot2-Base, the lower base chassis:
1. 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking
2. Onboard modules like line tracking, obstacle avoiding, needs no messy wiring
3. TB6612FNG dual H-bridge motor driver, compared with L298P, it's more efficient, more compact, and less heating
4. N20 micro gear motor, with metal gears, low noise, high accuracy
5. Onboard RGB LEDs, true color lighting, pretty cool

AlphaBot2 for micro:bit, the upper adapter board for controller:
1. micro: bit dedicated connector, for easily connecting with the micro:bit
2. MP1584 voltage regulator, provides stable 5V output
3. RT9193-33 voltage regulator, provides stable 3.3V voltage to the micro:bit
4. TLC1543 AD acquisition chip, allows the micro:bit to use analog sensors
5. PCA9685 PWM control chip, I/O expander
6. Onboard buzzer to play music
