Questions
How big is the HomePad PCB?
It measures 80.3 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HomePad use?
62 parts, built around the ESP32-C3-WROOM-02-H4, SN74LVC1T45DCK, TLV1117-33DCY 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 HomePad KiCad files?
From the strifel/HomePadV2 repository on GitHub, at the commit this page was made from: the board is HomePad.kicad_pcb and its schematic HomePad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HomePad design in my own project?
Its repository states no licence, so its author keeps all rights: ask strifel before reusing the design.
