It is a 75% layout, mechanical keyboard with hot-swap sockets! A rotatory encoder and an OLED screen!
I made this project because I love keyboards. This would be my second keyboard after a split one! This version runs on QMK firmware and also has a rotatory encoder with an OLED screen
PCB
The PCB is designed to be compatible with Cherry MX switches and features hot-swappable kalih sockets.

Questions
How big is the Shadowkeeb PCB?
It measures 332.5 × 116.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shadowkeeb use?
171 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 Shadowkeeb KiCad files?
From the Shadow220108/ShadowX75 repository on GitHub, at the commit this page was made from: the board is PCB/Shadowkeeb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shadowkeeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Shadow220108 before reusing the design.
