Overview
Keeb is an open-source printed circuit board by M0HID, from the M0HID/keeb-pcb repository on GitHub. It is a 2-layer board with 136 parts on 107 nets, routed with 1,648 tracks and 30 vias.
It is built around the ATMEGA32U4. Its parts include 63 switches, 61 diodes, 7 capacitors, 2 resistors and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

This is a keyboard PCB designed to accomodate cherry mx switches. It is a 65% layout (no function key row) I created this keyboard as i didnt have any good reliable portable keyboard that was comfortable to type on, so by making this i hope to solve that. I will create this PCB hopefully using hackclub onboard, and then assemble it myself
Features
- Atmega 32U4 microcontroller
- USB-C!
- Rotary encoder (with switch!!)
TODO
- Add RGB backlighting!!
- Oled screen (SSD1306 0.91")
- A case?

Questions
What parts does the Keeb use?
136 parts, built around the ATMEGA32U4. 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 Keeb KiCad files?
From the M0HID/keeb-pcb repository on GitHub, at the commit this page was made from: the board is keeb.kicad_pcb and its schematic keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask M0HID before reusing the design.
