Motoron M1U256 Single Serial Motor Controller

The Motoron M1U256 is a compact single-channel motor controller that drives a DC motor bidirectionally via a simple UART serial interface. With support for 4.5V to 48V and up to 2.2A continuous current, it handles everything from small hobby motors to larger industrial applications.

Unlike traditional motor drivers requiring PWM outputs, the Motoron uses serial commands, freeing up GPIO pins. Multiple controllers can share a single serial bus for multi-motor systems.

Key Features
