PWM DC Motor Speed Controller Module, 6–28V, 3A, 80W

This adjustable PWM DC motor speed controller provides smooth regulation for DC motors and other DC loads. Capable of handling up to 3A continuous current across a 6V to 28V DC input range, it delivers a wide duty cycle adjustment from 5% to 100%. It is well suited for hobbyist robotics, maker projects, and electronics workshops.

Pulse-width modulation control

The module regulates motor speed using a 21kHz PWM frequency with a duty cycle adjustable from 5% to 100%. This ensures efficient speed management for compatible DC loads without sacrificing torque.

Power specifications

Operating across an input supply range of 6V to 28V DC, the controller supports up to 80W of maximum output power. It reliably delivers a maximum continuous output current of 3A.

Wiring and safety recommendations

The board is not reverse-polarity protected and will be damaged if input power is connected incorrectly. Using an appropriately rated fuse is recommended, and all wiring should be verified before applying power.
