Custom USB keyboard
ZKeysPCB is an open-source printed circuit board by zchen24, from the zchen24/ZKeys repository on GitHub. It is a 2-layer board of 92.1 × 42.5 mm with 16 parts on 30 nets, routed with 49 tracks and 0 vias.
Its parts include 6 switches, 2 resistors and 1 IC. It belongs with the NXP (LPC, Kinetis, i.MX RT) boards of this library.
Custom USB keyboard (6-keys). The keyboard uses a Teensy LC microcontroller and 6 Cheery MX keys. I have programmed the keys to be media keys.

The 12 most common of 16 parts.
It measures 92.1 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
16 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 zchen24/ZKeys repository on GitHub, at the commit this page was made from: the board is ZKeysPCB/ZKeysPCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask zchen24 before reusing the design.
