The 2-Channel 12V Relay Module lets an Arduino or Raspberry Pi control two devices independently while powering the relays from a 12V supply. Each relay works like an electronically controlled on/off switch, so your code can toggle two separate loads from simple GPIO trigger signals. It is ideal for small control panels and automation builds where you already have 12V power available and want clean, reliable switching for things like lights, pumps, fans, valves, or solenoids.

I paired this with a 5V power supply, and an ESP32 and I can now control some 5V USB LED lights for my plants. The relays work as expected, the labeling is clear where the wires should go and I've had no issues controlling hardware with them. It's got circuit isolation which is nice if you're using higher voltage or amperage circuits. In my case everything is 5V DC but it's still nice to see. According to the label on the relay you can do 10A at 120V AC so you could make a smart power switch, but I haven't tested the AC capability of the relays.

It works great. I’m using this for an Arduino projects so nothing really difficult.

I'm using it with an Arduino on my model railroad to turn sections of track on and off automatically.

This great little board features to relays for controlling two inputs. You have two 5V triggers with optocouplers to avoid noise and the included LED lights tell you which Relay is on at a given time. This board has many uses... Great price too.

This dual 24-volt relay module is a necessity when it comes to creating DIY electronic projects. Whether you have a raspberry pi or arduino project this module will work for you. Because of the modules small size it can be added to many of your DIY projects especially those that space is a concern. I have installed it into a project, and I can say I have purchased many more expensive relay modules in the past, but this one seems to be operating wonderfully just as good (if not better) and at the cost it is definitely worth adding to your supplies.
