Questions
How big is the Door lock PCB?
It measures 84.8 × 49.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Door lock use?
66 parts, built around the CH32V003F4U6, MAX485ED, XL1509-5.0 and AMS1117-3.3. 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 Door lock KiCad files?
From the abiduldul/Door_lock repository on GitHub, at the commit this page was made from: the board is Hardware/Door_lock.kicad_pcb and its schematic Hardware/Door_lock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Door lock design in my own project?
Its repository states no licence, so its author keeps all rights: ask abiduldul before reusing the design.
