There are no retrigger contacts, just bare solder pads.

They work as long as you don't bother changing the trigger mode. Why? Because the ones I received didn't actually have "H/L" jumpers. They were just bare pads. I made a jumper on one of them to set it to "L", the pad came off immediately. It's pretty annoying. I only need to fire it once when there is movement, so now I have to change my code to only fire on the rising flank.

Pros

Stylish and modern design

Cons

I have no particular complaints about it, everything is fine
