This add-on board enables a compatible Raspberry Pi (Model B+ or newer), including the Pi 3 Model B+ and Model A+, to drive a pair of brushed DC motors. Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor. The default pin mappings make it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications. This version ships as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in.

Wide operating voltage range: 5 V to 28 V
Output current: 3 A continuous (5 A peak) per motor
PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
Motor indicator LEDs show what the outputs are doing even when no motor is connected
Board can optionally power the Raspberry Pi base directly through added 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
Remaining motor driver pins are exposed for advanced use
Reverse-voltage protection on motor supply
Robust drivers:
- Transient operation (< 500 ms) up to 40 V
- Internal peak-current limiting gracefully reduces the output power if the current or temperature get too high
- Under-voltage shutdown
- Output short-to-ground and short-to-Vcc protection
Prototyping space for easier/cleaner construction of custom circuits

This version of the motor driver is a partial kit, with connectors included but not soldered in. (See PO2756 for an assembled version.)
