Questions
What parts does the Home use?
46 parts, built around the ESP32-WROOM-32U, AMS1117, ULN2003A and EL814. 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 Home KiCad files?
From the ellectra2025-arch/PCB306 repository on GitHub, at the commit this page was made from: the board is home.kicad_pcb and its schematic home.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Home design in my own project?
Its repository states no licence, so its author keeps all rights: ask ellectra2025-arch before reusing the design.
