Questions
How big is the ESP32 PCB?
It measures 52.1 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 use?
27 parts, built around the CH340C, ESP32-WROOM-32, AMS1117-3.3 and SS8050. 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 KiCad files?
From the darshudarshans1122/PCB-Design-Portfolio repository on GitHub, at the commit this page was made from: the board is ESP32/ESP32.kicad_pcb and its schematic ESP32/ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask darshudarshans1122 before reusing the design.
