Custom wireless 65% compact keyboard made by Henry Wauzivuff.
Features
- Wireless potential + Rechargable battery slot
- 65% compact
- Joystick (my replacement of the Thinkpad trackball)
- 1x EC11 Rotary Encoder
In a future design, I hope to include a usb hub, on/off switches, LEDs & whatever makes better use of the IO expander I ended up using

Questions
How big is the Keeby PCB?
It measures 315 × 119.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keeby use?
154 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 Keeby KiCad files?
From the HEofOttoman/keeby repository on GitHub, at the commit this page was made from: the board is schematics/keeby.kicad_pcb and its schematic schematics/keeby.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keeby design in my own project?
Its repository states no licence, so its author keeps all rights: ask HEofOttoman before reusing the design.
