Questions
How big is the Esp32-thing PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32-thing use?
42 parts, built around the CP2102N-A01-GQFN24, ESP32-WROOM-32, SHTC3 and AP9211. 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 Esp32-thing KiCad files?
From the Stary2001/esp32-thing repository on GitHub, at the commit this page was made from: the board is esp32-thing.kicad_pcb and its schematic esp32-thing.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-thing design in my own project?
Its repository states no licence, so its author keeps all rights: ask Stary2001 before reusing the design.
