⚡ Switch smarter, not harder — reliability you can trust!
The HiLetgo 2pcs 5V One Channel Relay Module features a genuine quality relay capable of switching up to 10A at 250V AC or 30V DC. It incorporates SMD optocoupler isolation for stable, noise-resistant operation and a fault-tolerant design that prevents unintended switching if the control line fails. With selectable high or low level trigger modes and convenient screw terminal connections, this compact module (50x26x18.5mm) is perfect for professional-grade automation and control projects.

Easy to use.
As long as you have a multimeter this is one of the most reliable relay switches I have used. I have it sealed in a large shrink-wrap tube filled with hot glue freely mounted to the side of my bike.

So far its good!
With the caveat that its only been running a few hours, seems good so far. Very simple and easy to connect to my 3.3 Volt Arduino Nano 33. I used 5 volts to power the relay and a 3.3v pin for signal and that seems to work just fine. If I wanted to nitpick, it would be nice if it had solder holes and not just screw terminals. Screws are good for my breadboard prototype; not so much on my final design. So I will try to remove the screw terminals by de-soldering.

Works perfectly
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.

NOT Self-Latching/True Bistable
Works well, but it is NOT a bistable/self-latching relay. Requires power for the NO contact to remain closed after engaging the relay (and the opposite for the NC contact). The control line (marked "IN") must be held to the same level as the jumper to keep the relay engaged, i.e. if the jumper is L, IN must be 0V/Ground/Low, if the jumper is H, IN must be 5V/High. Info: 5V relay uses 1ma with relay off and 64ma with relay on. I'll probably find a use for these relays, but I am disappointed that they are not true self-latching relays. I don't know the duty cycle of the relay, but it gets slightly warm after a minute, and I've left it on for at least 10 minutes straight so far with no problem.

Reliable
As per usual another solid product from HiLetgo. I have been ordering from them since 2020 quite often. It started out because of the price and reviews mostly good. Now I always try and use this company from resistors to diodes to relays ect. I've only received 1 bad ESP32 and all it took was a soldering iron and 30 seconds and I was on my way. I ordered their relays 3 years ago and the same ones are going strong. So; I ordered these and wasn't let down upon opening.

Controlled by a Raspberry Pi. I have not electrocuted myself yet!
I connected the unit to a Raspberry Pi Zero 2W, in order to turn on the 120v main for a UV LED outdoor light project. The DC+ went to the 5v pin (Pin 4) The DC- went to a ground pin (Pin 6) The IN went to GPIO4 (pin 7) The COM went to the Black (HOT) line on the 120v plug. The NO went to the Brown (LOAD) wire on my voltage converter. The 120v Plug's White (Neutral) line is connected to the blue line on the voltage converter. A python script on the Raspberry Pi runs every 5 minutes during the hours between 6pm and midnight via the cron function. The script turns on the converter for 2 minutes and then lets the LEDs cool for 3. Voltage converter link: https://www.amazon.com/dp/B01N5SJ72Y

Works as intended
Relay worked exactly as predicted, came with great tech specs

Works great for Raspberry Pi, not great for AC voltage
Opens/shuts just like you want with raspi pin out signal, not a huge delay, but not the fastest. Very audible click sound when engaged or disengaged. Screw down wire clamps are very poor quality, you'll have to deal with wires slipping out a lot. After I accidentally shorted 15 amps of 120v AC power through one of these relays, it failed in the closed position, meaning the circuit was stuck active, even when the relay clicked "off." This actually caused me to get shocked, which I didn't find very funny at the time, but my fault for shorting that much power through the relay I suppose. So pair these with a 5 amp fuse to protect them, (and yourself.)

Connected this relay to Shelly Uni to be able to opens my front door remotely. Works really well
