Overview
My keeb is an open-source printed circuit board by Fungichi, from the Fungichi/KEEB repository on GitHub. It is a 2-layer board of 242.8 × 92 mm with 66 parts on 62 nets, routed with 191 tracks and 0 vias.
Its parts include 32 switches and 28 diodes. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdFatman 1.0
My DIY mechanical keyboard (sandwich mount). It has 28 keys of which 4 are 3u keys. This keyboard is especially designed to play games that were meant to be played on a *controller: each key replaces a part of the controller. It is ideal for rhytm games, Tetris, Mortal Kombat and many other retro games.
Why
My goal was to get a first feeling with hardware/pcb's. I think this is the perfect project to start with pcb's because the electronics part was pretty simple. That aside I do regret spending so much time on the case, as I think this is rather boring.
The result
The keyboard will be shown down below when I get the parts. What I learned:
- What makes up a keyboard
- How a switch matrix is constructed
- Making schematics in KiCad 10.0
- Designing the pcb in KiCad 10.0
- Designing an object in Onshape

Questions
How big is the My keeb PCB?
It measures 242.8 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the My keeb use?
66 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 My keeb KiCad files?
From the Fungichi/KEEB repository on GitHub, at the commit this page was made from: the board is pcb/my-keeb/my-keeb.kicad_pcb and its schematic pcb/my-keeb/my-keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the My keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fungichi before reusing the design.
