## Blueprint

**Schematics published.** Espressif publishes official schematic, PCB-layout, and mechanical DXF PDFs plus chip datasheets; no editable KiCad/Eagle/Altium source or Gerbers are released for this board.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-S3 | SoC | https://documentation.espressif.com/esp32-s3_datasheet_en.pdf |
| ESP32-S3-WROOM-1 / WROOM-1U | module | https://documentation.espressif.com/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf |

_Notes:_ All dl.espressif.com and documentation.espressif.com PDFs verified 200 via curl -sIL. espressif/esp-dev-kits (Apache-2.0, confirmed via gh api) hosts the user-guide docs, pin-layout and block-diagram images, but the tree has no .kicad_*/.SchDoc/.PcbDoc/gerber files for this board — only PNG/JPG diagrams and .rst docs, so it's listed as role 'docs', not hardware source. An unofficial community Altium recreation (Yousef4008/ESP32-S3-DevKitC-1-PCB) exists but is not from Espressif and was excluded.
