Waveshare AlphaBot2 Robot Building Kit for Arduino Overview This AlphaBot2 robot kit is designed to use with an Arduino compatible controller (not included). 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, youre 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, its 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-Ar, the upper adapter board for controller: 1. Onboard Arduino interface, into which Arduino controller can be directly plugged 2. 0.96inch 128x64 yellowblue dual color OLED 3. TLC1543 AD acquisition chip 4. PC8574 IO expander, avoid IO shortage 5. Xbee connector, for connecting dual-mode Bluetooth module Package Contents 1. AlphaBot2-Ar (adapter board) x1 2. AlphaBot2-Base (base chassis) x1 3.
