Which file should I download?
Head over to the releases section. There, you can find the latest release and it's Case.zip and PCB.zip files. Download and extract them and you'll see a 2k and 3k folder in each archive. Depending on your desired amount of keys, use the files in that folder.
Project Structure
The root folder of this repository is split into two folders, Latest and Older Versions. It is advised to only use the latest files.
Latest contains the files for the newest version of the minipad PCB and Case.
Older Versions contains a number of folders representing older releases of the PCBs and Cases.
Inside each versions folder you can find a PCB folder, containing a 2k and 3k folder for the two variants of the keypad, and a Case folder, containing the .stl files for the 3D-print.

Questions
How big is the Latest PCB?
It measures 63.5 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Latest use?
39 parts, built around the RP2040, W25Q128JVSIQ, GH39FKSW and SRV05-4. 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 Latest KiCad files?
From the minipadKB/minipad repository on GitHub, at the commit this page was made from: the board is Latest/v1/PCB/3k/KiCad Files/project.kicad_pcb and its schematic Latest/v1/PCB/3k/KiCad Files/project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Latest design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
