Questions
How big is the Esp32 PCB?
It measures 21 × 35.1 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Esp32 use?
45 parts, built around the ESP32-S3FN8, RCLAMP0521P.TCT-MS, AP2114H-3.3TRG1 and TP4056-42-ESOP8. 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 MyNameIsTobi/ESP32_TestBoard repository on GitHub, at the commit this page was made from: the board is Esp32.kicad_pcb and its schematic 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 MyNameIsTobi before reusing the design.
