I am building a cnc router and want to put all the electronics in a PC case and use the pc power button to power on the 24 pin breakout board. I wanted to use a pc power supply to power some of the electronics and a relay to turn on the other power supplies. I have very limited knowledge of electronics and after looking around I found this sparkfun benchtop power board kit
The problem I am having is that it uses a SPDT switch and I want to use the pc case switch. Then I found this board and thought I could get it to work.
It didn’t work and I am not sure if I wired it wrong or to much voltage so I am here asking for help.
