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.
What do COM, NO, and NC mean? They are the switched load terminals. COM is common, NO is normally open, and NC is normally closed.
