The Motoron M3H550 Triple Motor Controller makes it easy to control DC motors from a Raspberry Pi (Model B+ or newer) through an I2C interface. Each module can independently control up to three motors, and multiple Motoron boards can be stacked on top of the same Raspberry Pi for projects that need to control even more motors. The M3H550 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 soldered stackable headers and terminal blocks.

The Motoron M3H550 add-on board makes it easy to control up to three bidirectional, brushed DC motors with a compatible Raspberry Pi (Model B+ or newer). It operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor. The M3H550 is designed to stack on top of a Raspberry Pi (Model B+ or newer), similar to a HAT (Hardware Attached on Top), and 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 expansion boards for Raspberry Pi, the Motoron does not require any PWM outputs on your Raspberry Pi. Instead, the Raspberry Pi communicates with the Motoron using I2C, so only two GPIO pins are needed regardless of how many Motorons you connect.

This version of the Motoron M3H550 ships with soldered stackable headers and terminal blocks. It includes a set of two M2.5 standoffs (11 mm length), screws, and nuts that can be used to secure the board at the proper height for the GPIO connector.
