Ukiha

Small key pitch 5x12 ortholinear keyboard.

What is the Ukiha?

The Ukiha is a 5x12 ortholinear keyboard like the Preonic and JJ50, but with a smaller key pitch of 16mm instead of 19.05mm.

I like expantable keyboard boards like SU120 and te96, but in this case I designed a keyboard that I genuinely wanted.

The Ukiha (浮葉) means "floating leaf" and is taken from the Japanese classic, Pillow Book (枕草子).

In the book, there is an example of a very small floating lotus leaf taken from a pond as a lovely thing.

うつくしきもの。(中略) 蓮の浮葉のいとちひさきを、池より取りあげたる。(枕草子 第百五十一段より)

Why open source?

Anyone interested in small key pitch keyboard could try.

Customizability

The 4 keys in the middle of the bottom row can be replaced with 2U.

You can take off the top row and make it into a 4x12 keyboard like Planck and JJ40.
