Expandable keyboard PCB with up to 120 keys.
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.
