Keyboard
Really happy with what I made. I might update the art on the PCB, but I just wanted to get this in so I could make sure everything is good!
This is a keyboard I made it has a couple rotary encoders a screen and a whole lotta keys. I decided to make this because I kinda always wanted to make my own keyboard and was planning on using my onboard for that, but then this came up!

Questions
How big is the Keyboard PCB?
It measures 348.2 × 129.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
294 parts, built around the SK6812MINI-E. 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 Keyboard KiCad files?
From the jpt1729/keyboard repository on GitHub, at the commit this page was made from: the board is PCB/keyboard.kicad_pcb and its schematic PCB/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask jpt1729 before reusing the design.
