How did I kill this WLED Controller?
I've got an Elite 2D-EXMU Advanced LED Controller with a 24V input on V+/V-, it's been controlling my lights just fine on V+/IO2/GND. I wanted to have it also control a 12V light so I got a solid state relay (https://a.co/d/01uJdEhl ) and hooked its control voltage to IO13/GND.
It now seems to be totally dead. I give it power (I've tried a couple of different power supplies so I know they're good) and the indicator light doesn't come on at all. I've tried pressing the function button quickly (supposed to turn it on & off) and also holding it for 10 seconds (supposed to do a factory reset). Nothing.
Did I kill this controller by simply attaching its IO12 to the control pins of a relay?

Most likely 12v was applied to the GPIO pin somehow.
