Questions
How big is the ESP32 PCB?
It measures 32 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 use?
50 parts, built around the BQ27441DRZR-G1A, ESP32-C3FH4AZ, TP4054 and 1N5819WS. 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 edatki/Quectowatch repository on GitHub, at the commit this page was made from: the board is ESP32/Hardware/Hardware.kicad_pcb and its schematic ESP32/Hardware/Hardware.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 edatki before reusing the design.
