Review on π GeeekPi Raspberry Pi Expansion Board 4 Channel Relay Board - Power Relay for Raspberry Pi 4B, 3B+, 3/2B (No Programming/Programmable) by Darryl Blumenthal
Fits and works great
Fits and works perfectly. The LED indicators show very well that the relay is energized. The included hardware worked as expected and there were no issues with it. Only issue is currently unavailable and not sure if they will be back in stock. I hope they will.
