AlphaBot2 Robot Building Kit Based On BBC Micro:Bit (micro:bit nie je sucastou)

This AlphaBot2 robot kit is designed to use with the BBC micro:bit. 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.

Controller Introduction

The BBC micro:bit is an open development board that allows you to run code on it and have access to all of the hardware.

You can use your BBC micro:bit for all sorts of cool creations, from robots to musical instruments – the possibilities are endless. This little device has an awful lot of features, like 25 red LED lights that can flash messages. There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. Your BBC micro:bit can detect motion and tell you which direction you’re heading in, and it can use a low energy Bluetooth connection to interact with other devices and the Internet.

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
