Questions

How big is the Door bug PCB?

It measures 56.4 × 56.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Door bug use?

13 parts, built around the TSSP4038 and BC547. 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 bug KiCad files?

From the DanElbert/esp_bug repository on GitHub, at the commit this page was made from: the board is circuits/door_bug_circuit/door_bug.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Door bug design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
