DC motor speed controller

The NEWNEWLIU PC-2004 regulates DC motor speed from 6 V to 28 V with a 3 A current limit. PWM adjustment is handled by an onboard potentiometer and a built-in switch provides forward, reverse and stop control. An LED indicator shows power status and speed level. The module measures 50 mm by 32 mm by 0.59 mm and weighs 0.032 kg.

Hobbyists and small-project builders

Suits makers controlling fans, fish-tank pumps or similar low-power DC motors up to 80 W. Not for anyone needing AC mains input, automotive-voltage systems or motors drawing more than 3 A.

6 V to 28 V input range

The controller only operates within this DC voltage window; connecting it directly to 220 V AC will destroy the unit. Verify your power source stays inside the stated range before wiring.

Questions about this item

What physical space does the 50 mm × 32 mm × 0.59 mm board need to fit inside my enclosure?

The controller measures 50 mm long, 32 mm wide and 0.59 mm thick, so allow at least that footprint plus clearance for wiring and the potentiometer shaft.

Which wiring step is most often done wrong when installing the PC-2004?

Reversing the DC supply polarity — connecting positive to negative — will damage the board, so verify the wiring order before powering on.

What part of the PC-2004 will need attention or replacement over time?

The potentiometer and the built-in direction switch are the only moving parts; if speed control becomes noisy or direction changes fail, replace the controller.
