Check out my journal of mkaing this in the JOURNAL.md File!
A DIY ReallY cool mecahnical wired keyboard with backlighting which doesnt use an mcu! (Uses an atmeg32u4 chip inside, NEEDED TO MAKE MY OWN MCU INSIDE MY PCB).
🔥 Whats cool in this keyboard:
- Almost Fully cnc'd aluminium anodized parts for smooth good finish.
- A fully TPU Gasket mounted keyboard!
- A 65% keyboard which does have the function keys, numpad but still has the arrow keys!
- Full neopixels RGB backlighting for extra aesthetics 🌈.
- Fully custom design, no mcu which saves place in the keyboard. it uses and embedded chip and crystal and stuff inside the PCB (USING QMK firmware).
- Compact and ergonomic. Has a 5 degree tilt for better posture for wrists. Only about 3cm thick on the higher angeled side.
- USB-C on the side for less wiring.
- Has a rotatory encoder in it for volume/brightness control.
- Ig cheap for a premium custom cnc'd keyboard.

Questions
How big is the KeeBoard PCB?
It measures 351.9 × 99.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KeeBoard use?
273 parts, built around the ATMEGA32U4-AU and WS2812B. 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 KeeBoard KiCad files?
From the scattercat-123/KeeBoard repository on GitHub, at the commit this page was made from: the board is pcb-files gerbers & kicad/kicad/KeeBoard.kicad_pcb and its schematic pcb-files gerbers & kicad/kicad/KeeBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KeeBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask scattercat-123 before reusing the design.
