Building a GK21S numeric mechanical keypad with Gateron clears, Uniqey QMX, Domikey Dolch SA keycaps @kodabar

Have you ever wanted a separate numeric keypad? The GK21S comes with Bluetooth (up to three hosts), USB C socket, detachable cable, CNC aluminium case, Kailh hotswap sockets, tools and a soft case/sleeve. I ordered mine from KPRepublic on AliExpress and got a set of Gateron clear switches and Domikey SA Dolch Orange keycaps with it.

I used Elite Keyboards Switch Hitter for testing (Elite are sadly gone now) which you can download here:

I made a custom layout for the GK21S for Switch Hitter. Get that along with my other layout files and various ones I've collected here:

Music is Electronic P Disco Accordion by Frank Nora and is in the public domain, so I'd better not get any copyright nonsense yet again.
