Questions
How big is the Aek PCB?
It measures 437.9 × 148.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aek use?
243 parts, built around the ATMEGA32U4-MU and WS2812B. 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 Aek KiCad files?
From the djvs/aek repository on GitHub, at the commit this page was made from: the board is aek.kicad_pcb and its schematic aek.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aek design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
