PWM DC Motor Speed Controller 5A

This RioRand 1-OPKL-8L-5A module adjusts the speed of DC brush motors and the brightness of LED strips using a 10 kHz PWM signal. It accepts a 3 V to 35 V input range and delivers a 1 % to 100 % duty cycle for smooth, linear control. A built-in 5 A resettable fuse provides overcurrent protection that automatically resets after cooling. The package contains two identical controllers for parallel projects.

Compact 30 mm x 24 mm x 15 mm Board for Tight Builds

Each controller weighs 15 g and fits into small enclosures, freeing space for other components in robotics, automotive mods or DIY electronics. The board operates in two voltage modes: a default 5 V to 35 V range and a short-contact 3 V to 15 V mode for low-voltage loads. Reinforced soldering and individual functional testing support stable long-term operation. Wiring connects directly to the motor and power supply without extra adapters.

Makers Needing Simple Brushed Motor or LED Dimming

This suit builders who want plug-and-play speed control for DC brush motors, cooling fans or LED lighting within the 5 A limit. It is not for brushless motors, loads exceeding 5 A, or systems requiring closed-loop feedback or higher voltage rails. Users needing isolated control interfaces or programmable profiles should look at more advanced modules.

商品問答

Will the 5 A resettable fuse trip during continuous full-load operation?

The controller is rated for 5 A at up to 35 V; the built-in resettable fuse disconnects only on overload and resets after cooling.

Does the board run hot or need extra cooling when driving a motor at 35 V all day?

The compact 30 mm × 24 mm × 15 mm plastic housing has no heatsink; sustained high-current use may require additional airflow.

What power supply and motor type must I already have to use this module?

A DC source between 3 V and 35 V and a brushed DC motor or compatible DC load such as a fan or LED strip.
