5.0 out of 5 stars Great product so far
Reviewed in Canada on 6 November 2020
I am posting this review after my initial test since I won't be able to use it for some time. The board works great and easy to setup. I control it with python using code that I created for the Raspberry Pi Gertboard. I think the posted online manual is not accurate in terms of the GPIOs that are used (at least in my case), but that is not a problem. I used my multimeter and figured it out. In case it might help someone, here is what I found:
GPIO4 is Relay 1
GPIO22 is Relay 2
GPIO6 is Relay 3
GPIO26 is Relay 4

One thing to note is that I couldn't use it with any of my Pi cases. I can only use the base of the case (see the pictures), but that's not an issue.
