BSides Vancouver
The May 25-26, 2025 BSides Vancouver edition whose official 2025 badge archive identifies an electronic badge, links a first-party programming bundle, and directs badge information to a public source archive. The public hardware documentation calls the production board REV 2 dated 2025-05-05, while the visible refactor was committed in 2026 and is not treated as proof of a 2026 electronic-badge reissue.

BSides Vancouver's official 2025 badge page calls the artifact an electronic badge, links its first-party programming bundle, and directs firmware information to a public project archive. That archive documents a 2025 REV 2 board and a public firmware refactor committed in 2026, so this record separates the completed 2025 artifact from the later source-tree revision.
Lifecycle
The later source archive documents NFC tag interactions, LED progress indicators, sensors, optional Wi-Fi control-panel behavior, and a mini-CTF. The catalogue preserves that high-level feature surface while refusing to call it the exact factory image or reproduce programming and challenge instructions.
The public hardware reference describes a 100 mm × 100 mm board, ESP32-C3FH4, ST25R3911B NFC reader, RGB and charlieplex LEDs, sensors, buttons, USB edge connector, and CR2032 holders, and calls the PCB REV 2 dated 2025-05-05. This is linked as a technical documentation trail rather than a production audit or safety certification.
The repository README and workshop guide describe a hands-on badge-workshop package with a starter template and source material. The record keeps this as source-published workshop context; no reviewed organizer source proves every session date, participant count, or completed workshop outcome.
The organizer's own repository describes files for programming the BSides Vancouver 2025 Electronic Badge and lists a bootloader, partition table, badge binary, and helper script. It establishes an official programming bundle without exposing a versioned source release, deployment ledger, or individual recipient record.
The archive's history places the initial public refactored v2.4.0 source and workshop docs on May 29, 2026, with related v2.4.1 and deck updates through June 1. It increases transparency around the 2025 board but does not establish a 2026 badge reissue or production-firmware parity.
The public archive declares an MIT license for software and associated documentation under BSides Vancouver Society copyright. This is a source-license record, not an automatic reuse clearance for every photograph, board-art layer, logo, physical artifact, or event mark that may appear around the project.
Operational history
The record does not backdate later source improvements into the delivered 2025 image or treat public 2026 commits as evidence of a separate 2026 conference badge.
The catalogue links valuable source and binary evidence without asserting a current, authenticated, supported, or universally deployed firmware image.
The Canada record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
No safety, battery-life, interoperability, or reliable wireless-operation claim is inferred from the visible board documentation.
Source-backed board details remain useful without becoming a claim of every produced badge's exact bill of materials, layout, quality, or final physical state.
The catalogue records a real 2025 electronic badge without asserting that every ticket holder received one or that a particular source bundle was flashed onto every physical unit.
The record may link the software and documentation license while keeping visual, branding, physical-artifact, and local-image reuse claims deliberately scoped.
