channel SunFounder 5V 8 Channel Relay, which stopped working and I'm not sure if because something I did: The first time I connected to my pi everything worked, I powered the board from 5v pin of the pi and all 8 relays nicely clicked and turned on/off the built in leds, I didn't try with any other load.
Then I spent some time wiring up the rest of my setup (trying to build controllable power outlets) and when I was ready to test everything (meaning pi+relay board-outlets but not connected to AC) the leds are still lighting up but there is no switching.
Can it be that I damaged/scratched/burnt anything? I tried different power supplies, another pi board, but still nothing...
To clarify my question little bit, was the fact that it originally worked just a random luck? indeed I've read many similar treads about not enough power etc but at the same time have seen several successful cases. So wanted to know what could've changed between my 2 tries...
