README
READMELimousine is a drop in PCB replacement for Keychron Q9. This layout is intended to support a 30% layout plus right-side numpad. -Hotswap MX switch sockets -2u or split backspace -Right side numpad with 2u or split 0. -Traditional row stagger or alpha stagger layout options -Multiple bottom row layout options including 7u, 10u (with 7u stabilizer mounts), 6u, split 2.25u/2.75u, and a solder only split 3u option -Two EC11 push button encoders positions, both iterchangeable with hotswap MX switches NOTE: The split 3u spacebar option is included to accomodate layouts with dedicated left hand mods. It requires soldered switches for the spacebar positions and removal of the hotswap socket for the 2.75u right spacebar position.

Questions
How big is the Limousine PCB?
It measures 309.6 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Limousine use?
191 parts, built around the RP2040, W25Q128JVSIQ 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 Limousine KiCad files?
From the baconspoon85/Limousine repository on GitHub, at the commit this page was made from: the board is limousine-pcb/limousine.kicad_pcb and its schematic limousine-pcb/limousine.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Limousine design in my own project?
Its repository states no licence, so its author keeps all rights: ask baconspoon85 before reusing the design.
