## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    High build quality, very useful.  Fits in Hammond enclosure card slots.
  

*by L***O on Reviewed in the United States on May 18, 2018*

These are super handy for photon projects that require 12v power and isolated switching.  I found out by happy accident that the board will fit perfectly into the card slots in a Hammond enclosure part number 1554S2GY (check Mouser or Digikey)

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great for automated and manually controlled relays
  

*by J***B on Reviewed in the United States on November 11, 2019*

This is a great little relay panel. Can be used with automation apps managed through Particle's online dashboard or utilize a "manual" activation of relays using the Tinker function on your phone's Particle photon app.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great Add-on to the Photon
  

*by D***Y on Reviewed in the United States on August 22, 2017*

I am a huge Particle Photon fan and love these boards. The relay board is a great add-on. The library provided by Particle is easy to use. I have also partnered this board with the Power Shield for even greater flexibility.
