Compact DC Motor Power for Prototypes, Small Drives, and Repairs
The DC Motor Speed Controller PWM 4.5V-35V 5A 90W is a practical dc motor from Circuitrocks for students, makers, and repair-friendly builds. It fits well in projects that need simple spinning motion, while keeping setup straightforward for testing and prototype work.
Compared with generic parts, this product stands out through details such as 4.5V, 35V, 5A. That makes it a solid choice for Arduino, ESP32, Raspberry Pi, robotics, motion-control, and workshop projects where matching the right part from the start saves time.
Important: Always match the electrical rating, size, and control method of this part with the rest of your setup before full-power testing.
Why you'll love it
- 4.5V: gives you a quick spec reference before choosing the right part
- 35V: gives you a quick spec reference before choosing the right part
- 5A: gives you a quick spec reference before choosing the right part
- 90W: gives you a quick spec reference before choosing the right part
- PWM: adds useful value when choosing parts for a build
- Simple spinning output: adds useful value when choosing parts for a build
What you can build
This product is a good fit for small spinning mechanisms, fans, drive experiments, and compact electromechanical builds. It works especially well in student projects, quick repairs, and prototype builds where part availability, straightforward hookup, and predictable results matter.
Starter bundles
Plan for a matching power supply, a proper driver stage where needed, and a controller if you want timed, remote, or sensor-based operation.
Recommended add-ons
Useful add-ons include drivers, propellers, couplers, mounts, and stable external power. You can also compare it with DC Motor Speed Controller DC 6V-90V 15A, DC Motor 130.

Frequently Asked Questions
Can this work with Arduino or similar boards?
Yes, as long as the voltage, control method, and wiring match your controller and power supply.
Should I power it directly from a controller pin?
For small signal-only modules that may be fine, but motors, pumps, solenoids, and relays should use a proper driver or external supply.
Is this good for student and prototype builds?
Yes. It fits well in testing, learning, and proof-of-concept projects when matched with the right support parts.
How do I choose the right version?
Check the size, voltage, torque, speed, current, and fit details that matter most for your project.
