Questions
How big is the ESP32 Dev Kit PCB?
It measures 47 × 29.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 Dev Kit use?
26 parts, built around the CP2102-GMR, ESP32-WROOM-32 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 ESP32 Dev Kit KiCad files?
From the BrijModi/ESP32-Dev-Kit-Clone repository on GitHub, at the commit this page was made from: the board is ESP32 Dev Kit.kicad_pcb and its schematic Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Dev Kit design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrijModi before reusing the design.
