Two-channel driver of direct current (DC) motors with an operating voltage from 6 to 30 V and a maximum continuous current of 20 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron MDD20A

This controller allows independent control of three DC motors using a single I²C bus. It supports motor supply voltages ranging from 4.5 to 44 V and currents up to 0.8 A continuous per channel, making it suitable for a wide range of robotic and mobile applications. I²C communication eliminates the need to generate PWM signals and significantly saves microcontroller pins. The ability to connect multiple controllers on a single bus allows for easy scaling of the system to larger motor counts. Pololu 5084
