OFFZONE 2026

The completed August 20-21, 2026 OFFZONE edition at GOELRO in Moscow, anchored by the official conference site's 2026 recap of roughly 3000 participants and 130+ speakers. A first-hand attendee toolkit documents the event's STM32 serial-console badge, while organizer pages themselves do not mention the badge.

OFFZONE 2026 Badge

An OFFZONE 2026 conference badge documented through a first-hand attendee toolkit: an STM32 board with a USB Virtual COM Port exposing a built-in serial console with led, echo, and mini-game commands, four addressable LEDs driven by an official bytecode format distributed with the badge docs, and animation sequences verified byte-for-byte on real 2026 hardware.

OFFZONE 2026 Badge note

single-source artifact boundary · first-hand attendee toolkit plus official event page · organizer badge statement outstanding

The badge is documented only through a first-hand attendee toolkit; the official OFFZONE site never mentions it, and no organizer archive, schematic, photo rights, production count, or allocation statement was recovered.

The catalogue records the observed badge console and LED system without asserting organizer design intent, quantities, ticket-class scope, or any official firmware release.
