Research 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.

Maker listing checked Sep 15, 2026. Detailed documentation reviewed Sep 15, 2026. Not hands-on tested.

Price is a dated listing; confirm with the maker.

This entry follows the v1.1 guide. Both original and v1.1 boards exist; the RGB LED pin differs.

WROOM-1U uses an external antenna connector. Octal-memory variants reserve GPIO for memory, so choose the module before designing attached hardware.

Amazon link points at the listing the 2026-09-17 research identified as official or authorised; this category is full of clone hardware, so never swap it for a search result.
