From the project

YUIOP: Etude of designing keyboards

YUIOP keyboards are experimental original keyboards designed by KoRoN.

* yuiop27/ - separate keyboard prototype.

* yuiop54/main - signle board keyboard prototype.

combined right and left-hand boards of yuiop27. PCB dimension is 285.00mm x 94.60mm (GH60 compatible form factor without screw holes).

* yuiop54/main2 - researching version of yuiop54.

multi-sheets schematic. fix layout for auto routing. introduce GND cupper fill. * rev.B - trial to make compatible with GH60 (include screw holes).
