Minimal development board for an ESP32-S3 MCU.
It contains the following elements:
- ESP32 MCU with all available pins broken out
- Programming header with DTR/RTS mechanism
- Power LED
- Fuse to prevent the worse
- Jumper to disconnect 3v3 from the programmer to be able to test e.g. battery mode while still debugging

Questions
How big is the Esp32-s3-dev board PCB?
It measures 30.8 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-s3-dev board use?
15 parts, built around the ESP32-S3-WROOM-1-N8R8 and UMH3N. 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-dev board KiCad files?
From the chof747/esp32-s3-dev-board repository on GitHub, at the commit this page was made from: the board is esp32-s3-dev-board.kicad_pcb and its schematic esp32-s3-dev-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-s3-dev board design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
