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:

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

AlphaBot2 for micro:bit, the upper adapter board for controller:

• micro:bit dedicated connector, for easily connecting with the micro:bit
• MP1584 voltage regulator, provides stable 5V output
• RT9193-33 voltage regulator, provides stable 3.3V voltage to the micro:bit
• TLC1543 AD acquisition chip, allows the micro:bit to use analog sensors
• PCA9685 PWM control chip, I/O expander
• Onboard buzzer to play music
