The Motoron M2S24v16 Dual High-Power Motor Controller Shield for Arduino makes it easy to control two high-power DC motors from an Arduino or Arduino-compatible board through an I²C interface. The M2S24v16 supports motor supply voltages from 6.5 V to 40 V and can deliver continuous output currents up to 16 A per motor. This version is just the motor controller by itself, without any header pins or terminal blocks included.
