Commit-pinned official Apache License 2.0 text for the public nsec/badge-2026 repository, used as the reuse basis for the repository's selected front-board source render.
Official build configuration for the C++/Arduino PlatformIO source tree. The repository also carries conference/CTF partition material and source modules, but this source does not establish a tagged or physically deployed event firmware image.
Official source header mapping ST25R3916 NFC, the 200×200 GDEH0154D67 / SSD1681 e-paper path, six buttons, and eighteen WS2812/NeoPixel LEDs on the ESP32-S3 design.
Official hardware directory whose README identifies the NorthSec 2026 badge design. It contains KiCad board and schematic files, JLCPCB BOM/CPL/Gerber production material, dock hardware, and source artwork; it proves a public post-event design archive, not a per-recipient production configuration.
Official source SVG for the NorthSec 2026 front-board artwork. The catalogue's local image is a high-resolution raster export of this exact vector, with NorthSec repository attribution, Apache-2.0 license basis, and processing notes recorded in BadgeImage metadata.
The historical nsec/nsec-badge archive rechecked on 2026-08-03 had no 2026 branch, tag, or dedicated hardware tree. That finding applies only to the legacy archive and is no longer an official-2026-source gap: NorthSec separately published nsec/badge-2026.
MIT-licensed source image for the official repository photo of the NorthSec 2023 conference badge PCB; used only for image provenance, not as a standalone hardware-spec source.
MIT-licensed source image for the official repository photo of physical NorthSec 2021 badge variants; used only for image provenance, not as a standalone hardware-spec source.
MIT-licensed source image for the official repository photo embedded by the 2017 badge website as two badges connected together; used only for image provenance, not as a standalone hardware-spec source.
MIT-licensed official repository source GIF for the NorthSec 2024 badge image; the local WebP uses the first frame as an optimized static delivery image.
License metadata source for treating the hw/2025 badge render and hardware files as MIT-licensed NorthSec repository material.
Official NorthSec 2026 badge source snapshot at commit 4dab9e6c4c0b8efc9a643ee646a49550453ea22c. The public repository appeared on 2026-08-03 after the May event, carries Apache-2.0 licensing, and had no tagged release, GitHub release, or published binary at review time. Its earlier authored commits record development history, not prior public availability.
