Questions
How big is the Doorman PCB?
It measures 37.1 × 37.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Doorman use?
44 parts, built around the ESP32-S3-WROOM-1-N8R8, AP63203WU, GAQY252G3S and CC0603KRX7R9BB104. 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 Doorman KiCad files?
From the AzonInc/Doorman repository on GitHub, at the commit this page was made from: the board is pcb/doorman.kicad_pcb and its schematic pcb/doorman.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Doorman design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
