The CADLAB README describes a 39x9, 351-LED matrix as the badge's main display surface.
Operational history
Issues & Camp Impact
The badge archive proves the badge hardware and 2019 Pixels Camp relationship; separate event sources prove the March 21-23, 2019 Lisbon event details.
The dossier keeps hardware claims tied to the project archive and event claims tied to Pixels Camp and Portuguese event coverage.
The public README states the firmware goal and custom-firmware possibility, but the current source trail does not prove a final attendee firmware release, app ecosystem, or shipped software image.
The catalogue describes the software surface conservatively as an intended web-connected scrolling-text target.
The CADLAB project shows images and renders, but no image is published because badge.gallery still needs an explicit reusable license, attribution string, source URL, and processing notes for any public badge image.
The Portugal badge record remains source-backed and image-free rather than copying CADLAB, event, or press imagery without complete rights provenance.
