Frequently Asked Questions

How do I connect and set up the relay module?

Connect the control pins to your microcontroller digital outputs using TTL logic (active low), supply 5V power to the board, and wire your high-voltage appliances to the relay terminals following safety precautions.

What should I do if a relay channel does not trigger?

Check your microcontroller wiring, ensure the trigger pin is pulling LOW as required by the active-low logic, verify that the 5V power supply is stable, and check the LED indicators to see if the signal is reaching the board.

Which microcontrollers are compatible with this board?

This module is compatible with a wide range of microcontrollers including Arduino, AVR, PIC, ARM, 8051, DSP, and MSP430 using a standard interface.

Are spare parts and additional electronic components available?

Yes, common electronic components, jumper wires, and replacement modules can be ordered through our store as needed for your projects.

What is included in the package and what else do I need?

The package includes the 4 Channel 5V Relay Module Board. You will still need jumper wires, a 5V power source, a compatible microcontroller like an Arduino, and high-voltage cables or appliances for your project.

Does the 4 Channel 5V Relay Module Board for Arduino and Microcontrollers come with a warranty?

Yes. Warranty cover applies, up to 24 months depending on the product, and our team provides sales, servicing and spare parts support. Confirm the exact period when ordering.
