Questions
How big is the MiniPC PCB?
It measures 145.7 × 82.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniPC use?
72 parts, built around the ESP32-WROVER-B and WS2812B. 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 MiniPC KiCad files?
From the apuder/MiniPC repository on GitHub, at the commit this page was made from: the board is kicad/pc/v0.2/MiniPC.kicad_pcb and its schematic kicad/pc/v0.1/MiniPC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniPC design in my own project?
Its repository states no licence, so its author keeps all rights: ask apuder before reusing the design.
