Questions
How big is the Esp PCB?
It measures 80 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp use?
54 parts, built around the ESP32-WROOM-32, DS1302S+T&R, TPS566231RQFR 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 Esp KiCad files?
From the technoparrot01/indicatron repository on GitHub, at the commit this page was made from: the board is pcb/esp/esp.kicad_pcb and its schematic pcb/clock/indicator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp 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).
