This AlphaBot2 robot kit is designed to use with an Arduino compatible board UNO PLUS. It features rich common robot functions including line tracking, obstacle avoiding, ultrasonic ranging, infrared remote control, Bluetooth communication, 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 Chassis:

  • 5-channel infrared sensor, analog outputs. Used with PID algorithm provides stable line tracking
  • Onboard builtin modules like line tracking, obstacle avoiding, needs no messy wiring
  • TB6612FNG dual H-bridge motor driver, compared with L298P, are more efficient, more compact, and run cooler
  • N20 micro gear motor, with metal gears, low noise, high accuracy
  • Onboard RGB LEDs, true color lighting, interactive indication

AlphaBot2-Ar, the Upper Adapter Board for Controller:

  • Onboard Arduino interface, into which Arduino controller can be directly plugged
  • 0.96inch 128x64 yellow/blue dual color OLED
  • TLC1543 AD acquisition chip
  • PC8574 I/O expander, avoid I/O shortage
  • Xbee connector, for connecting dual-mode Bluetooth module


UNO PLUS Features:

UNO PLUS is a development board designed by Waveshare and compatible with the Arduino UNO R3. It is improved & enhanced alternative solution for Arduino UNO R3.

UNO PLUS Vs Original UNO R3:

Operating voltage 5V/3.3V 5V Dual voltage level to support more shields
Reset Lateral Vertical Lateral button is easier to use when connecting with shields
Bootloader switch Yes None The board can be configured to run program immediately when power-up by the switch
USB connector Micro USB USB Type B Micro connector is more commonly used, and shields won't be blocked anymore when connected
DC jack Low profile Normal height Shields won't be blocked anymore when connected
Power output header Yes None

Providing 5V/3.3V power output OR common-ground with other boards

3.3V power regulator 800mA Max 150mA Max UNO PLUS features higher driving capability 3.3V regulator
Oscillator Crystal oscillator Ceramic resonator Crystal oscillator is suited for applications where a more accurate clock reference is needed
ADC channels 8 6 CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN
Connecting with prototype breadboard Supported Not supported Solder pads is provided for DIY interfaces to connecting with prototype breadboard
USB driver Compatible with all main systems Doesn't compatible with WIN7/WIN8 Express Edition Driver will never failed to install thanks to the onboard FTDI FT232 IC (all OS built in drivers)
Firmware fixing Supported Not supported Firmware can be fixed by using the onboard FT232, no extra programmer is needed
