Questions
How big is the ESP32-S3 PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.58 mm thick.
What parts does the ESP32-S3 use?
52 parts, built around the ESP32-S3-WROOM-1-N8, SI7021-A20-GM, LM1117-3.3 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 ESP32-S3 KiCad files?
From the ysaip07/KiCAD_Project repository on GitHub, at the commit this page was made from: the board is ESP32-S3/ESP32-S3.kicad_pcb and its schematic Astable Multivibrator/Astable_Multivibrator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ysaip07 before reusing the design.
