The Motoron M2U256 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using a UART serial interface. Multiple Motoron controllers can be connected to the same serial bus, making it easy to expand a system with additional motors. The M2U256 supports motor supply voltages from 4.5 V to 48 V and can deliver continuous output currents up to 1.8 A per motor. This version ships with header pins included but not soldered in.
