Frequently Asked Questions

Q: What voltage range does this PWM DC motor speed controller support?

A: This PWM DC motor governor controller supports an input voltage range of 6V to 24V DC, making it compatible with a wide variety of hobby power supplies, battery packs, and bench supplies commonly used in electronic projects.

Q: How does the forward and reverse switch function work?

A: The controller uses a relay-based forward/reverse switching mechanism. By toggling the switch, the relay reverses the polarity delivered to the motor, instantly changing its rotation direction. This is ideal for applications like robotic arms, conveyor systems, or any build requiring bi-directional motor control.

Q: What is the maximum current this controller can handle?

A: The PWM DC motor speed controller supports a maximum continuous current of 3A, which is suitable for driving small to medium-sized DC motors commonly used in hobbyist and maker projects.

Q: Is this controller compatible with Arduino or Raspberry Pi projects?

A: Yes! This compact PWM motor governor is well-suited for use alongside microcontroller platforms like Arduino and Raspberry Pi. It can be integrated into your project enclosure thanks to its small 57mm × 37mm footprint.
