Expandable keyboard PCB with up to 120 keys. main image

What is the SU120?

The SU120 is an assemblable and expandable keyboard PCB with biscuits, screws and wire.

I use JIS Kana input method, but at that time I couldn't find split JIS keyboard PCBs.

So I designed the PCB to make the keyboard layout easy to trial and error.

You may make Row-Staggered, Column-Staggerd, Ortholinear, or other layouts keyboard.

SU is Japanese homophones: 州(sandbank) and 鬆(porous).

Why open source?

Anyone interested in keyboard could try the keyboard layout more easily.
