Overview
Minidox is an open-source printed circuit board by PhhDD, from the PhhDD/Deepi repository on GitHub, published under the MIT licence. It is a 2-layer board of 81.5 × 120.6 mm with 53 parts on 59 nets, routed with 392 tracks and 28 vias.
It is built around the ATMEGA32U4-AU. Its parts include 16 diodes, 7 capacitors, 7 resistors, 2 switches and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

My first customised wireless mechanical split keyboard, modified based on the open source Minidox keyboard
- Includes a pcb design, outer case design
- Also includes a keymap
- Parts need to be purchased separately
Based on this, a more minimalistic design was made with only 34 keys, however this one is kept private as the keymap contains macros with sensitive information
Here is a photo of the keyboard :)

Questions
How big is the Minidox PCB?
It measures 81.5 × 120.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minidox use?
53 parts, built around the ATMEGA32U4-AU. 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 Minidox KiCad files?
From the PhhDD/Deepi repository on GitHub, at the commit this page was made from: the board is Minidox/Minidox.kicad_pcb and its schematic Absonity/Abson/absonity.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minidox design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
