And make sure you don’t wire them backwards, or else you might get a funny smell and little wisps of black smoke leaking out from your keyboard. ![20190330_142819%5B1%5D](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/c/d/d/cdd90b47030818434db6540cd038f9c3e1b4b2a3.jpeg) On the bright side, having to order a new PCB means I get to build a 2nd keeb from scratch 😁 I figure that I can just buy a new cap for this fried PCB and that should get it working again. ---
