DC 6–30V PWM Motor Speed Controller — 10A Reversible Switch Module
Compact
PWM DC motor speed controller designed for smooth variable-speed control of compatible
DC brushed motors with built-in
forward / stop / reverse switching. This module combines a
potentiometer speed knob, a
reversible direction switch, and onboard protection features in one practical DIY control board.
It is ideal for
small motor projects,
robotics,
fans,
pumps,
DIY machinery, and other low-voltage DC applications where adjustable speed and reversible direction are needed.

Quick Selection Guide
Need adjustable speed for a DC brushed motor? This module is a good fit.
Need forward and reverse rotation? The included switch gives
direction control plus center stop.
Need precise regulated DC output voltage for electronics? Choose a true
DC voltage regulator / converter instead.
Need to drive heavy or continuous loads near the limit? Stay closer to the
6A recommended range and provide airflow if needed.
🎛
How to Use
1. Connect a compatible
DC 6–30V power source with correct polarity.
2. Connect the motor to the output terminals.
3. Set the reversible switch to
forward,
stop, or
reverse.
4. Turn the potentiometer knob to adjust motor speed.
5. If direction is opposite of what you expect, change the switch position or motor lead sequence as needed.

Typical Uses
DC brushed motor speed control
DIY robotics and motion projects
Small fans and blowers
Low-voltage pumps
Mini conveyor / hobby machine projects
Workshop and maker electronics builds
🔌
Wiring & Safety
Use a
DC power supply only within the
6–30V range.
Do
not reverse the DC input polarity; even with protection, correct wiring is always best practice.
The center position of the reversible switch is the
stop / zero position.
This controller is intended for
compatible DC brushed motors.
For heavier loads, provide adequate wiring gauge, proper fusing, and airflow if needed.
Do not use on AC mains or with unknown motor types.
⚠️
Important Notes
Maximum current is listed as
10A, but
6A is the recommended working level.
Actual usable output depends on
input voltage,
motor load,
wiring quality, and
cooling.
This module controls motor speed through
PWM duty adjustment; it is not the same as a precision variable DC power supply.
