These don't fit the wires you'd typically use in a Arduino project because they are too small but it's really easy to just desolder the connecter and solder your wires directly.

There are a lot of reviews for these clearly written by people using them in ways they are not intended to be used.I am using these to trigger different animatronics from an ESP32. I have 3 of them run in parallel with a 3v LED at the end of the chain. I am powering them from the ESP32's 3V3 pin. I am using a GPIO as the trigger. The ESP32, connected via usb to a computer, still provides enough amperage to trigger all 3 at the same time in addition to powering the LED.The relays support 250V@30A on the output side ONLY. Some people mentioning theirs caught on fire, but clearly are running voltage to the wrong rails.There's no documentation on the jumpers, but basically they are ground and VCC. I am not sure why they would be there, but I guess you could use them as headers to not use the screw terminals? this seems silly though as IN would still need to use the screw terminal.Overall these work great for my project.

Can be used from a ESP32 system which has 3.3V logic without any additional circuitry. Has screw terminal blocks for both sides of the relay making it easy to integrate with microcontroller board. Has a red LED that lights when the relay is activated, giving good operational feedback.Only niggle is that the screw holes are a bit small. i had to enlarge them with a file to fit normal sized standoff screws.

These relays have a nice skinny form factor and can be attached directly to 3.3V tolerant GPIO.The only negative is that the M2.5 mounting holes are too close to the edges of the board. Hardly any material forms the holes and cracking is a concern.

They come attached, but are easy to split off individually if needed. They’re working great, controlled by simple GPIO pins from an ESP32 board.
