The Motoron M3S256 Triple Motor Controller Shield for Arduino makes it easy to control DC motors from an Arduino or Arduino-compatible board through an I²C interface. Each module can independently control up to three motors, and multiple shields can be stacked on top of the same Arduino for projects that need to control even more motors. The M3S256 operates from 4.5 V to 48 V and can deliver continuous output currents up to 2 A per motor. This version ships with a variety of header pin and terminal block options included but not soldered in.

Overview

The Motoron M3S256 shield makes it easy to control up to three bidirectional, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime. 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 shields, the Motoron does not require any PWM outputs or timers on your Arduino. Instead, the Arduino communicates with the Motoron using I²C, so only two I/O lines are needed regardless of how many Motorons you connect.

Three M3S256 versions are available to provide different options for the through-hole connectors:

For applications using a Raspberry Pi, consider the Motoron M3H256 instead (also available with different connector options).

Motoron M3S256 Triple Motor Controller Shield Kit for Arduino.

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

There are more parts 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 a shield 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 shields, 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).

The Motoron family

The table below lists the members of the Motoron family and shows the key differences among them. Each type is available in three versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with stackable headers and terminal blocks soldered in, as a kit with connectors included but not soldered in, or as a standalone board without connectors.
