Adjustable DC Motor Speed Controller – Potentiometer Knob, Linear Output, 1.8–15V, 0–2A, For 3V–12V Low-Voltage Motors

About This Product

If you're tinkering with small DC motors, this little speed controller is super handy.
It takes input from 1.
8 to 15 volts DC and gives you a linear output with adjustable current up to 2 amps – continuous at 2A, so it handles most hobby and light machinery motors.

The potentiometer knob lets you dial in speed smoothly from zero to max, giving you precise control.

It's compact too – just 32x32x15mm with a 26x26mm mounting footprint – so it fits easily into tight enclosures or panels.

The 7mm hole in the panel accepts standard knobs (not included), which makes for a clean, tactile setup.
Works great with 3V, 5V, 6V, 8V, and 12V motors.
Built with sturdy terminal blocks for secure connections, and the design is stable and reliable over repeated use.

Perfect for robotics, model trains, fans, or any project where you need to vary motor speed.
Easy to wire, easy to use – a solid little workhorse for makers and hobbyists.
