This ANSI/ISO keyboard kit is made using ONLY through hole components and inspired by the Plaid.
Atmega328p with VUSB on QMK firmware.
To alter the pcb use KiCAD V5.0 or newer as it already contains most of the libraries. The additional libraries are provided.

Questions
How big is the Gingham PCB?
It measures 285.8 × 123.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gingham use?
173 parts, built around the ATMEGA328-PU. 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 Gingham KiCad files?
From the yiancar/gingham_usbc_pcb repository on GitHub, at the commit this page was made from: the board is pcb/gingham.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gingham design in my own project?
Its repository states no licence, so its author keeps all rights: ask yiancar before reusing the design.
