MC33926 Dual Motor Driver Hat for Raspberry Pi - 3A

RASPB-002755


This add-on board enables a Raspberry Pi B+, A+, or Pi 2 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 motor driver board is an add-on for the Raspberry Pi Model B+, A+, or Pi 2 that lets it easily control a pair of bidirectional, brushed DC motors. The expansion board uses a pair of Freescale MC33926 motor drivers, which operate from 5 to 28 V and can deliver a continuous 3 A per channel (up to 5 A per channel for a few seconds). Other features include a reverse battery protection circuit and logic gates that reduce the number of I/O pins required to control the driver ICs effectively.

Features:

  • 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
