Introduction

The Motoron M3H256 add-on board enables you to easily control up to three bidirectional brushed DC motors through a compatible Raspberry Pi (Model B+ or newer). It supports motor supply voltages from 4.5 V to 48 V and can deliver up to 2 A of continuous output current per channel. The M3H256 is designed to stack on top of a Raspberry Pi (Model B+ or newer) in a manner similar to a HAT (Hardware Attached on Top), and multiple Motoron controllers can be stacked on top of each other for independent control of multiple motors. Unlike most motor drivers and motor driver expansion boards for Raspberry Pi, the Motoron does not require any PWM output from the Raspberry Pi. Instead, the Raspberry Pi communicates with the Motoron via I²C, so only two GPIO pins are needed regardless of how many Motorons are connected. This version ships with pre-soldered stacking headers and terminal blocks.

Features
