Unreliable Module, Waste of Money

This opto isolated trigger was a total waste of money. I bought it for my single board computer and it just didn't work well. I struggled to get it set up and when I finally did, it would randomly stop working. The one pro is that I appreciated the isolation feature, but it's not worth it if the module can't even function. Save your money and look for a different trigger.

Pros

Isolation feature

Cons

Unreliable and difficult to set up
