![[2-Pack] DC 5V Relay Module 2-Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger](https://images-na.ssl-images-amazon.com/images/I/71NNkhe7-5L._AC_UL165_SR165,165_.jpg)
Wiring was super intuitive and everything just worked. I was able to power, ground and provide signal all from Arduino and then pull 12V DC from a 4A dedicated power source and connect it directly to the 12V DC magnet when the relay receives a signal. Perfect solution for my secret bookcase door project!
Only note was that the relay screws needed the perfect sized screw driver because it felt like it was going to strip with the one little screwdriver I use for everything so I had to get a new small screwdriver kit and then i was able to repeatedly install and change configurations on this board without any problem.

Here is the schematic of the module
I've attached a photo of the relay module schematic. I Ohm'd and traced it out. Now the function of the 2-pin jumper is fairly clear. In my case, I want the coil to be active when the input (IN) is a logic high (3.3V) from an Arduino. Thus, I want the jumper as shown in the schematic (photo).

Fast and secure shipping in these. When I opened the package it was a pleasant surprise to find that the pieces were individually bagged in Mylar ESD protection packs. So far, I have only opened one and the quality feel of the plastic made me confident that I can trust that one to work. As the two-pack has two of the same items, I am just as optimistic the second one will perform in my hand the same.
Most easy hookups on this! See my schematic picture.
With the chip shortages and rising price of oil, I just know these can only go up in value. That brings me to the reason one star was deducted. These are currently being sold at the same price as I paid. Good news for you, bad news for me. Buyers, don’t miss out!
