The Motoron M3H550 add-on board makes it easy to control up to three bidirectional, brushed DC motors with a compatible Raspberry Pi (Model B+ or newer). It operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor. The M3H550 is designed to stack on top of a Raspberry Pi (Model B+ or newer), similar to a HAT (Hardware Attached on Top), and multiple Motoron controllers can be stacked on top of each other, allowing independent control of many motors. Unlike most of Pololu's motor drivers and motor driver expansion boards for Raspberry Pi, the Motoron does not require any PWM outputs on your Raspberry Pi. Instead, the Raspberry Pi communicates with the Motoron using I²C, so only two GPIO pins are needed regardless of how many Motorons you connect.

Three M3H550 versions are available to provide different options for the through-hole connectors:

For applications using an Arduino or compatible controller, consider the Motoron M3S550 instead (also available with different connector options).

Motoron M3H550 Triple Motor Controller Kit for Raspberry Pi.

This version of the Motoron is a kit that ships with the following connectors included but not soldered in:

It also includes a set of two M2.5 standoffs (11 mm length), screws, and nuts that can be used to secure the board at the proper height for the GPIO connector.

There are more connectors included than can be soldered to the board, providing different assembly options to suit a variety of applications. Additional connector options are available separately, and you can also solder wires directly to the board for more compact installations.

Note: For applications where the Motoron will be used as a standalone board or at the top of an add-on board stack, it can be assembled with the included 0.1" male header pins and larger (5.0mm-pitch) blue terminal blocks. For applications where the Motoron will be one of the intermediate members of a stack of add-on boards, Pololu recommend assembling it with the stackable headers and smaller (3.5mm-pitch) green terminal blocks (just like Pololu's version with connectors already soldered). The terminal blocks are intended to be soldered to the larger through-holes for the power and motor connections, and the blue ones should get locked together prior to installation (see Pololu's short video on terminal block installation).

  • PWM frequency: eight options available from 1 kHz to 80 kHz
  • Command timeout feature stops motors if the Raspberry Pi stops communicating
  • Configurable automatic error response
  • Motor power supply (VIN) voltage measurement
  • Optional pins make it easy to power the Raspberry Pi from reverse-protected motor power through an external regulator (not included)

  • Motor direction indicator LEDs
  • Motoron Python library simplifies using the Motoron with Python or MicroPython
  • Comprehensive user’s guide

The Motoron family

The tables below list the members of the Motoron family and show the key differences among them. Each type is available in several versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with connectors soldered in, as a kit with connectors included but not soldered in, or (for Arduino and Raspberry Pi expansions) as a standalone board without connectors.
