My idea for this was to try and make one of those fancy looking ergonomic keyboards with a pcb. I have seen some other designs just have each individual key have a separate housing for the shifting on each row of keys but i want to just make a few pcbs and connect them so this will be ortholinear with a curve in the board vertically and a thumb cluster. I designed a corne keyboard recently but the issue was I felt I did not have enough keys for what I wanted to do so here i have 5 rows of 7 keys and a thumb cluster with 5 keys meaning 40 keys per half of the board or 80 total.

Questions
How big is the CurvoBoard Split PCB?
It measures 314 × 144.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CurvoBoard Split use?
314 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CurvoBoard Split KiCad files?
From the Jyst7/CurvoBoard-Split repository on GitHub, at the commit this page was made from: the board is PCB/CurvoBoard Split.kicad_pcb and its schematic PCB/CurvoBoard Split.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CurvoBoard Split design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jyst7 before reusing the design.
