Questions
How big is the Esp32-s3-development board PCB?
It measures 66 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-s3-development board use?
47 parts, built around the ESP32-S3-MINI-1-N8, AP2112K-3.3, DMG3414U and WS2812B. 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-development board KiCad files?
From the ginomcfino/esp32-dev-board repository on GitHub, at the commit this page was made from: the board is hardware/esp32-s3-development-board.kicad_pcb and its schematic hardware/esp32-s3-development-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-s3-development board design in my own project?
Its repository states no licence, so its author keeps all rights: ask ginomcfino before reusing the design.
