PCB designed to match this case.
Uses the QMK firmware, my fork of which is here: https://github.com/SirEelBiscuits/qmk_firmware/tree/garnet
As yet, keyboard and keymap are not merged upstream.

Questions
How big is the Lets split PCB?
It measures 124 × 85.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lets split use?
60 parts. 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 Lets split KiCad files?
From the SirEelBiscuits/lets-split repository on GitHub, at the commit this page was made from: the board is lets-split.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lets split design in my own project?
Its repository states no licence, so its author keeps all rights: ask SirEelBiscuits before reusing the design.
