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-PiZero, the upper adapter board for controller:
• LM2596 voltage regulator, provides the Pi with stable 5V power
• TLC1543 AD acquisition chip, allows the Pi to use analog sensors
• PCA9685 servo controller, make it more smoothly to rotate the pan head
• CP2102 UART converter, easy for controlling the Pi via UART
• USB HUB chip, more USB ports for devices like NIC
