LCA2017 IoTuz ESP32 Board note

image provenance upgrade · official repository license and exact photo source · licensed original photo applied

The IoTuz visual uses the official `Case/Printable/front-shot.jpg` repository photo under the repository LICENSE statement covering photos and other documentation as Creative Commons Attribution Share-Alike 3.0.

The public badge page, image archive, and API now point at a real upstream IoTuz photo with source URL, license, attribution, and processing notes preserved.

LCA2017 IoTuz ESP32 Board note

revision and source-depth caveat · source-backed but historical · needs board-revision audit

The public trail proves the IoTuz project, board files, firmware, assembly guidance, and workshop use, but this pass has not audited exact production-run revision, BOM state, manufacturing quantity, or whether every repository image and file maps to the distributed boards.

The badge dossier cites public hardware and software archives while avoiding unsupported production-run claims.
