Overview
Lucenox is a custom mechanical keyboard with hotswappable switches which was inspired by the QWERTZ layout. It also features per key RGB with QMK!
Reason
I made the project just for fun and to see if I could build my own keyboard, because I wanted something that felt exactly like my current keyboard, but in a smaller size. Also I currently use a membrane keyboard and I thought that highway could give me an opportunity to learn how mechanical keyboards work and switch to a mechanical one.

Questions
How big is the Lucenox PCB?
It measures 348.5 × 118 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lucenox use?
253 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 Lucenox KiCad files?
From the lumentae/lucenox repository on GitHub, at the commit this page was made from: the board is PCB/Lucenox.kicad_pcb and its schematic PCB/Lucenox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lucenox design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
