Only 1 of the 3 modules I received worked properly. Upon further testing one of the non-working modules with a multimeter, I discovered that the push button switch was defective. I was able to just solder the right spots under the board to keep it powered up all the time and all I had to do was unplug or remove the jumpers to turn the power off. If only all three work properly and not just one, 5 stars.
