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 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 is just the motor controller by itself, without any 惩罚她给她用最粗的玉势h or mounting hardware included.
