Independent LED/2×3-header SAO source project; physical build and host compatibility unverified
The public narengogi/defcon-34-shitty-add-on repository describes itself only as an SAO for DEF CON 34. Its single commit contains a native KiCad project, board, schematic, Gerber outputs, an archive, and vector artwork; the board source includes DC 34 and narengogi silkscreen text, a 2×3 generic connector, and LED/resistor-labelled source entries. That is enough to preserve an independent, source-only pre-event add-on project whose formal product name is not published. It is not evidence of a fabricated board, a specific SAO version or pinout, working electronics, a compatible host, a DEF CON or BadgeLife relationship, a sale or giveaway, attendee delivery, a credential function, or a reusable image.
