Review: Seems to work with 3v logic level. Had some trouble with the inverse logic jumper. Looks like it floats and you need to use a pull-down resistor. When I did that 3v triggering stopped working though, so maybe the 5v rating refers to inverse logic mode?
Review: Works are expected. Happy with the performance.

### ⭐⭐⭐ Review
*by T***D on 13 June 2024*

Once of these modules was intermittently closing the relay with a 4.5V source, fully capable of 300mA+. Sometimes it wouldn't close, and the relay would need to be physically tapped for it to actually close. I measured the current to that whole module at 81mA when closed. Yes, that's not the full 5V, but I found it worrying. I replaced it with another module and the replacement was able to consistently close with a voltage all the way down to 3.8V. The draw on that module was 95mA. So these have a large variance in tolerance. You may want to test each module to see if it can handle small voltage sags.
