Review on Keyestudio 5V DCAC 4-Channel Relay Hat Shield Module Expansion Board for Raspberry Pi 4, A+, B+, Pi 2 Model B, Pi 3 Model B by George Bridgewater

Revainrating 3 out of 5

i have this wire

I don't know as there are different versions but the GPIOs don't match the online documentation when found. The one I have is hooked up like this. GPIO 4 - Relay 1 GPIO 22 - Relay 2 GPIO 6 - Relay 3 GPIO 26 - Relay 4. I'm a bit frustrated, I had to try all combinations to figure it out.

Pros
  • Not just usable for its intended purpose
Cons
  • I don't have much dislike for it, all fine
