Motoron M3H256 Triple Motor Controller Kit for Raspberry Pi
The Motoron M3H256 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 M3H256 supports motor supply voltages from 4.5 V to 48 V and can deliver continuous output currents up to 2 A per motor. This version ships with a variety of header pin and terminal block options included but not soldered in.

Notes:
- 1
- PCB assembly only, without optional included headers, terminal blocks, or standoffs.
- 2
- Absolute maximum; higher voltages can permanently destroy the motor drivers. Recommended maximum nominal battery voltage is approximately 36 V, which leaves a safety margin for ripple voltage on the supply line.
- 3
- Note: Reverse voltage protection only works up to 40 V.
