My first customised wireless mechanical split keyboard - minimalist 34 keys
Absonity 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 241.9 × 135.4 mm with 81 parts on 61 nets, routed with 710 tracks and 67 vias.
Its parts include 34 diodes, 2 switches and 1 IC. It belongs with the keyboards and input boards and the nRF52 and nRF5x boards of this library.
My first customised wireless mechanical split keyboard, modified based on the open source Minidox keyboard
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 :)

It measures 241.9 × 135.4 mm and has 2 copper layers, 1.6 mm thick.
81 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.
From the PhhDD/Deepi repository on GitHub, at the commit this page was made from: the board is Absonity/Abson/absonity.kicad_pcb and its schematic Absonity/Abson/absonity.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
