Notes: Original 592x1301 PNG community-badge board/artwork raster downloaded from the public ElectronicCats/Badge-bsides-cdmx-2025 repository and preserved in Public/images/source. The repository README identifies the design as the Security BSides CDMX 2025 Badge, lists the badge technology, and states the hardware is released under CERN Open Hardware Licence v1.2 with LICENSE_HARDWARE as the license file; this is an official upstream hardware-tree raster, not generated content, placeholder art, a social-media photo, or a screenshot. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Why It Mattered

It deepens the Mexico City coverage with a Security BSides badge whose official event page, open hardware repository, firmware tree, release binaries, BOMs, and licensed upstream community-badge render make both the artifact and its public provenance unusually strong for a regional LATAM BSides event.

Hardware

The README lists Puya PY32F030F28U6TR, NeoPixels, OLED display, two AAA battery holder, and Shitty Addon connector. The hardware tree preserves Community, Guest, Speaker, Sponsor, and Staff KiCad badge variants, board PNGs, silkscreen/edge-cut SVGs, footprints, STEP models, BOM release assets, and a separate Metro add-on with artwork and BOM release.

Software & Apps

The badge ships with pre-installed firmware according to the README, with release-section binaries for reprogramming. The firmware tree is based on a Puya PY32F0 template with GNU Arm Embedded Toolchain, J-Link or PyOCD programming, Makefile build/flash flow, CMSIS/HAL/LL libraries, and release HEX assets including `app.hex` and `Metro.hex`.

Lore

The official BSides CDMX page frames the fifth edition as a free community-driven Mexico City Security BSides event on July 18, 2025 at Ex Fabrica MX. The repository gratitude section asks attendees to tag Electronic Cats and BSides CDMX with their badge, tying the hardware to the public event identity.
