Frequently Asked Questions
Q: What voltage range does this MOSFET switch controller board support?
A: This 4-channel MOSFET PWM switch controller board supports a wide supply voltage range of DC 5V to 27V, making it compatible with most standard power supplies used in DIY electronics, automotive, and industrial control projects.
Q: Can I use this board with an Arduino or Raspberry Pi?
A: Yes! The board's optocoupler isolation allows it to interface safely with 3.3V or 5V microcontrollers such as Arduino and Raspberry Pi. Simply send a PWM or pulse signal from your microcontroller's GPIO pins to trigger each channel independently.
Q: What kinds of loads can this MOSFET controller board drive?
A: This module is well-suited for driving DC motors (fans, pumps, linear actuators), LED lighting strips, solenoids, and other DC resistive or inductive loads within the supported voltage range. Always check the maximum current rating of your specific MOSFET channels before connecting high-current loads.
Q: What is optocoupler isolation and why does it matter?
A: Optocoupler isolation uses light (LED + phototransistor) to electrically separate the control signal circuit from the load circuit. This protects your microcontroller or signal source from back-EMF, voltage spikes, and electrical noise generated by motors or other inductive loads, greatly improving reliability and safety in your project.
