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 without any header pins or terminal blocks included.

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 for Arduino (No Connectors).

This Motoron version is just the assembled PCB module as shown above, with no connectors included. This version is intended for those who mostly want to solder wires directly to the board or use different connectors from those included with other versions. We have a variety of connectors available separately.
