Waveshare AlphaBot2 Robot Building Kit For Raspberry Pi 3 Model B Overview This AlphaBot2 robot kit is designed to use with Raspberry Pi 3 Model B (not included). It features rich common robot functions including line tracking, obstacle avoiding, BluetoothinfraredWiFi remote control, video monitoring, 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. 5Onboard RGB LEDs, true color lighting, pretty cool AlphaBot2-Pi, the upper adapter board for controller: 1. LM2596 voltage regulator, provides the Pi with stable 5V power 2. TLC1543 AD acquisition chip, allows the Pi to use analog sensors 3. PCA9685 servo controller, make it more smoothly to rotate the pan head 4. CP2102 UART converter, easy for controlling the Pi via UART
