Overview
Fifi split keeb is an open-source printed circuit board by raychengy, from the raychengy/fifi_split_keeb repository on GitHub. It is a 2-layer board of 115.7 × 95.7 mm with 66 parts on 52 nets, routed with 1,333 tracks and 165 vias.
It is built around the SK6812MINI-E. Its parts include 18 diodes, 18 switches, 6 inductors, 4 connectors and 2 resistors. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

README.mdFifi Keyboard 🐶 ⌨️
The Fifi keyboard, named after my 🐶, is a split keyboard with 3x5 column staggered keys and 3 thumb keys, based on foostan's mini-crkbd schematic and thomasbaart's kyria layout.
The goal of this project was to build a split keyboard that fits perfectly for the miryoku layout with the minimalist style of mini-crkbd and have the aggressive column staggered keys found in kyria. The PCB is reversible, meaning you'll need two of the same PCB to create a full keyboard. It is my first attempt in PCB board design.
TODO
- Add tent puck support
- Add an additional key in the thumb cluster (support for rotorary encoder)
- Add 3D-printed case

Questions
How big is the Fifi split keeb PCB?
It measures 115.7 × 95.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fifi split keeb use?
66 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 Fifi split keeb KiCad files?
From the raychengy/fifi_split_keeb repository on GitHub, at the commit this page was made from: the board is pcb/fifi_split_keeb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fifi split keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask raychengy before reusing the design.
