Drop Ctrl Led Light issues
After a few months using my Drop Ctrl, the Z key doesn't light up anymore. Is there a way to tell if the led is dead or something? I've tried restarting the board and also reflashing the firmware that I'm using but to no avail the led doesn't turn on. Any help would be greatly appreciated.

You can try opening up the keyboard to check for visible damage to the LED leads. If there's no visible damage, chances are it's just a busted LED and there's not much you can do about it. Submit a ticket with CS to get the replacement process going.
