Questions
How big is the ESP32 Design PCB?
It measures 100.8 × 68.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 Design use?
73 parts, built around the CH340C, ESP32-WROOM-32D, LM2596S-5.0 and HDSP-7401. 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 Design KiCad files?
From the More414/PCB-designing repository on GitHub, at the commit this page was made from: the board is ESP32_Design/ESP32_Design.kicad_pcb and its schematic Ardino Nano ATMEGA328-p/Ardino Nano ATMEGA328-p.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Design design in my own project?
Its repository states no licence, so its author keeps all rights: ask More414 before reusing the design.
