Motoron M3S550 Triple Motor Controller Shield Kit for Arduino

The Motoron M3S550 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 supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 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 M3S550 versions are available to provide different options for the through-hole connectors:

• Motoron M3S550 with soldered stackable headers and terminal blocks
• Motoron M3S550 with headers and terminal blocks included but not soldered in
• Motoron M3S550 without any headers or terminal blocks included

For applications using a Raspberry Pi, consider the Motoron M3H550 instead (also available with different connector options).

This version of the Motoron M3S550 is a kit that ships with the following connectors included but not soldered in:

• One 1×10 stackable female header
• One 1×8 stackable female header
• Four 2-pin 3.5mm terminal blocks
• Four 2-pin 5mm screw terminal blocks
• One 1×25 breakaway male header (you can cut or break this into smaller header strips to install as desired)

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).

• Three motor control channels allow for independent control of up to three bidirectional brushed DC motors per Motoron
• Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum)
• Maximum output current per motor: 1.7 A continuous, 5 A peak for
