## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Nice module, works well
  

*by D***S on Reviewed in the United Kingdom 🇬🇧 on 21 August 2020*

Works well, does not get hot, low current requirement.  I bought this (as a pack of 3, now I have a couple of spares!) to construct a sensor to detect whether power had failed on a particular electrical circuit.  I powered the relay with an old 5V iPhone charger in series with a 22 ohm resistor.  The relay contacts which are isolated from the supply I connected to a GPIO pin on a Raspberry Pi, such that I can sense the relay state remotely.

### ⭐⭐⭐ 







  
  
    Only one worked; the other two didn't.
  

*by A***H on Reviewed in the United Kingdom 🇬🇧 on 11 July 2019*

Out of the box two were faulty. Found soldering on the circuit board poor and shorts between adjacent PCB pads. One faulty one had a solder bridge between the 5V and input and the other didn't have a pin on the relay soldered at all. I had to repair these two myself. Once I'd done this all three working. Beware - check for short circuits and solder splashes to avoid damaging your arduino pin.

### ⭐⭐⭐⭐⭐ 







  
  
    Tiny relay board
  

*by R***3 on Reviewed in the United Kingdom 🇬🇧 on 1 June 2019*

I needed a small relay board for my project, this does the job. The relay output offers ON\OFF connection, the relay is energised using a +5V signal.
