Motor Pro Shield
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.
- 4 Motor driver interface
- 4 Linker kit interface（ADC、UART、GPIO、PWM）
- 2 Ultrasonic interface
- 1 9-axis module interface
- 2 Infrared tube interface
- Independent switch for motor power supply
- Over current protection
