This compact expansion board plugs directly into the GPIO header on a Raspberry Pi and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its pair of integrated MAX14870 motor drivers allows it to operate from 4.5 V to 36 V, making it a great control option for small motors that run on a wide range of voltages. The board can deliver a continuous 1.7 A (2.5 A peak) per motor. This version ships fully assembled with connectors soldered in.
- Two single-channel H-bridge motor drivers with shoot-through protection and internal free-wheeling diodes (can each drive one DC motor)
- Motor supply voltage: 4.5 V to 36 V
- Output current: 1.7 A continuous (2.5 A peak) per motor
- Board can optionally power the Raspberry Pi base directly through add-on regulator (not included)
- Python library makes it easy to get started using this board as a motor driver expansion board
- GPIO pin mappings can be customized if the default mappings are not convenient
- Reverse-voltage protection on motor power supply
- Under-voltage lockout and protection against over-current and over-temperature
- Surface-mount resistor can optionally be added to enable automatic current limiting
