Inspiration
When I started looking for my first actual keyboard, I found out about StenoKeyboards, where a bunch of YouTube videos boast 200+ wpm typing speeds. However, after just getting a plain old mechanical keyboard, I forgot about StenoKeyboards for a long time. However, when I found out about Hackpad, I suddenly remembered StenoKeyboards and wanted to make one myself.
Extra notes
I'm going to change the firmware when I actually get the kb

Questions
How big is the Stenopad PCB?
It measures 269.1 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stenopad use?
85 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 Stenopad KiCad files?
From the B-Eddie/stenopad repository on GitHub, at the commit this page was made from: the board is pcb/Stenopad.kicad_pcb and its schematic pcb/Stenopad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stenopad design in my own project?
Its repository states no licence, so its author keeps all rights: ask B-Eddie before reusing the design.
