Questions
How big is the Esp32 IoT PCB?
It measures 83.9 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 IoT use?
41 parts, built around the ESP32-WROOM-32D, CH343P, AMS1117-3.3 and BC817. 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 IoT KiCad files?
From the Cath272/ESP32_Purple repository on GitHub, at the commit this page was made from: the board is esp32_IoT.kicad_pcb and its schematic esp32_IoT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 IoT 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).
