Frequently Asked Questions

Q: What can I control with a 4 Channel MOSFET PWM Switch Controller Board?

A: This board is ideal for controlling DC motors, LED light strips, solenoids, and other DC loads. Each of the four independent channels can be triggered via a PWM or pulse signal from a microcontroller such as an Arduino or Raspberry Pi, making it extremely versatile for automation and electronics projects.

Q: What voltage range does this MOSFET controller board support?

A: The board supports a wide supply voltage range of 3.7V to 27V DC, making it compatible with single-cell LiPo batteries, 12V automotive systems, and various bench power supplies typically used in DIY electronics builds.

Q: What is the benefit of the built-in optocoupler (opto-isolator)?

A: The integrated optocoupler provides electrical isolation between your low-voltage control signal (e.g., from a microcontroller) and the high-power load circuit. This protects sensitive components from voltage spikes, noise, and back-EMF, significantly improving the reliability and longevity of your overall system.

Q: How many boards do I need for a typical project?

A: One board provides four independent switching channels, which is sufficient for many standard projects. For larger builds requiring more than four channels, simply add additional boards. This product is available in convenient packs of 1, 2, or 5 units.
