Motor Pro Shield for pcduino
Contents
Introduction
Motor Pro Shield is a 4 channel motor driver board which bases on TI - DRV8801. Specifically for pcDuino users to make their own robots, this shield provides rich interfaces. This Motor Pro Shield is just compatible with pcDuino 2/3/3B.
- 4 x Motor driver interface
- 4 xLinker kit interface（ADC、UART、GPIO、PWM）
- 2 xUltrasonic interface
- 1 xIMU Interface
- 2 x Infrared sensor interface
- Independent switch for motor power supply
- Over current protection
