The Motoron M2U550 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using a UART interface. Multiple Motoron controllers can be connected to the same serial bus, making it easy to expand a system with additional motors. The M2U550 supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor. This version ships with header pins included but not soldered in.
