The Motoron M3H256 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 4.5 V to 48 V and can deliver continuous output currents up to 2 A per motor. Multiple Motoron controllers can be stacked on top of each other, allowing independent control of many motors. Unlike most of our 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 M3H256 versions are available to provide different options for the through-hole connectors:
For applications using an Arduino or compatible controller, consider the Motoron M3S256 instead (also available with different connector options).
This version of the Motoron is a kit that ships with the following connectors included but not soldered in:
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, we recommend assembling it with the stackable headers and smaller (3.5mm-pitch) green terminal blocks (just like our 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 our short video on terminal block installation).
