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 supports motor supply voltages 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.

Identifying markings

PCB dev codes: mc3s44a
Other PCB markings: 0J13968


PCB assembly only, without optional included headers and terminal blocks.
The IOREF pin should be between 3.1 V and 5.5 V: it supplies an LDO that produces the logic voltage, which is typically 3.3 V. The board is compatible with 3.3 V and 5 V I²C busses.
Reverse voltage protection only works up to 20 V.
