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
