Questions
How big is the Door Lock PCB?
It measures 38.5 × 47.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Door Lock use?
116 parts, built around the ESP-12F, LSM9DS1 and ULN2003A. 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 nsahadat/Fun_Projects repository on GitHub, at the commit this page was made from: the board is Door_Look/PCB_KiCAD/Door_Lock.kicad_pcb. 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 nsahadat before reusing the design.
