Overview

Product Overview

The ShillehTek 1-Channel 12V Relay Module lets an Arduino or Raspberry Pi control a single device like an electronically controlled on/off switch, while the relay itself is powered from a 12V supply. It is perfect for simple automation builds where you need one controllable output for a light, fan, pump, solenoid, or other load, using a basic GPIO trigger signal. This is a clean, beginner-friendly way to switch higher-power devices without building a relay driver circuit from scratch.

The relay's contacts are rated up to 10 A at 250 VAC or 30 VDC and exposed on NO/NC/COM screw terminals, with an indicator LED showing the switch state at a glance. The input triggers from 3.3 V or 5 V GPIO while the coil runs from your 12 V supply, making it a natural fit for automotive accessories, solar setups, and 12 V control panels that need one clean switched output.

Questions & answers

Frequently asked questions

Does this 12V relay module work with Arduino and Raspberry Pi?

Yes. It is intended for Arduino and Raspberry Pi projects where a GPIO pin sends the control trigger, while the relay module itself is powered from a 12V supply.

Is this relay module ready to wire into a project?

Yes. ShillehTek modules are sold pre-soldered for easier hookup, so you can focus on wiring power, the GPIO trigger, and the switched load instead of building a relay driver circuit from scratch.

What voltage powers this relay module?

The relay module is powered from a 12V supply. The Arduino or Raspberry Pi GPIO provides the control signal; it should not be used as the relay’s main power source.

Can this relay module control a fan or pump?

Yes. It can provide one controllable on/off output for a light, fan, pump, solenoid, or similar device. Always confirm the connected load is appropriate for the relay’s switching capability before use.

Why does the relay not click from my GPIO?

Check that the 12V relay power supply is connected, the GPIO trigger wire is on the correct input, and your code is changing the pin state. A GPIO signal alone will not power the relay coil.

Customer Reviews

It works great!

I’m using this for some simple Arduino projects so nothing really taxing on it. It works great.

A Solid Relay That Doesn’t Try to Be Fancy

This relay module works just as well as some of the name-brand options I’ve used. It’s reliable, responsive, and the ability to trigger via either high or low level inputs is a nice touch, especially if you want to build in a simple failsafe or just avoid logic headaches.The status LEDs are a welcome feature too. They make troubleshooting way easier when your circuit decides to play dead. It’s not flashy, but it’s a perfectly good relay for DIY projects, automation setups, or robotics.Pros:Supports both high and low level triggering; great for flexible circuit design.Status LEDs help with quick diagnostics.Works reliably with Arduino, Raspberry Pi, and PLCs.Comparable performance to more well-known brands.Cons:Nothing special in terms of design or features.Doesn’t come with documentation, but it’s straightforward enough.tldr:If you need a basic relay that works and doesn’t cost a fortune, this one’s a solid pick. It’s not going to impress your electronics professor, but it’ll get the job done.

Relay board with high voltage isolation

This little Relay controller board. Allows you to trigger heavier amperage attachments like motors lights with a simple 5 V trigger.. There are many uses for this. You just have to be creative. The board has great separations between high voltage and low voltage and it is isolated using a Optocoupler.
