Questions
What parts does the ChristmasPCB use?
33 parts, built around the ATTINY13A-SSU and IRLML0040TRPBF. 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 ChristmasPCB KiCad files?
From the Neposis/ChristmasPCB repository on GitHub, at the commit this page was made from: the board is ChristmasPCB.kicad_pcb and its schematic ChristmasPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChristmasPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Neposis before reusing the design.
