The Motoron M1U256 Single I²C Motor Controller offers a compact solution for controlling one DC motor 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 M1U256 supports motor supply voltages from 4.5 V to 48 V and can deliver continuous output currents up to 2.2 A. This version ships with soldered headers.
