Product Description
The Motoron M3S550 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 M3S550 operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor. This version ships with a variety of header pin and terminal block options included but not soldered in.
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 operates 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.
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)
