Questions
How big is the Esp-32 PCB?
It measures 33 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp-32 use?
21 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3 and WS2812B-2020. 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-32 KiCad files?
From the pakhi217/esp-32 repository on GitHub, at the commit this page was made from: the board is esp32.kicad_pcb and its schematic esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp-32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pakhi217 before reusing the design.
