Questions
How big is the ESP PCB?
It measures 50 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP use?
59 parts, built around the CP2104EK, ESP32-S3-WROOM-1-N8, BMI270 and USBLC6-2SC6. 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 KiCad files?
From the vadymtaranenko/ESP32-S3-DevBoard repository on GitHub, at the commit this page was made from: the board is Hardware/ESP.kicad_pcb and its schematic Hardware/ESP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP design in my own project?
Its repository states no licence, so its author keeps all rights: ask vadymtaranenko before reusing the design.
