Motoron M3S550 Triple Motor Controller Shield for Arduino (No Connectors)

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 just the assembled PCB module as shown above, with no connectors included. This version is intended for those who 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.

• 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
