Questions
How big is the Desktopia PCB?
It measures 59.1 × 49.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Desktopia use?
76 parts, built around the ATMEGA32U4-AU, CC6905S8-5FB005, TCA9554DB and TPS5430DDA. 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 Desktopia KiCad files?
From the Diabltica/Desktopia repository on GitHub, at the commit this page was made from: the board is hardware/desktopia.kicad_pcb and its schematic hardware/desktopia.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Desktopia design in my own project?
Its repository states no licence, so its author keeps all rights: ask Diabltica before reusing the design.
