Production files
The available files were generated to make the PCB by JLCPCB. Also, an Alps plate file is available in the folder Plates. Both folder of files have been tested and a complete keyboard has been made.
Firmware
A precompiled .uf2 file is available for programming via QMK Vial. Also a folder to produce the file via QMK is available (RP2040 QMK needed).

Questions
How big is the Keyboard PCB?
It measures 337.2 × 122.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
176 parts, built around the RP2040, W25Q128JVSIQ, SRV05-4 and XC6206P332MR. 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 Mattelec/Alicia 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 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).
