Product Description
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.)
