Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The README lists the Puya PY32F030F28U6TR microcontroller as the badge core, and the firmware README documents the PY32F0 MCU family and Cortex-M0+ build path.
Badge context
Raw README source for Puya PY32F030F28U6TR, NeoPixels, OLED display, AAA battery holder, Shitty Addon connector, preinstalled firmware note, release-binary path, gratitude, and hardware-license statement.
Official English event page source for BSides CDMX identity, fifth-edition context, July 18, 2025 date, Ex Fabrica MX venue, free community framing, and Mexico City Security BSides scope.
Repository releases preserving `app.hex`, `Metro.hex`, and BOM CSV assets for Community, Guest, Speaker, Staff, and Metro add-on outputs.
Firmware README source for Puya PY32F0 template, GNU Arm Embedded Toolchain, J-Link/PyOCD, Makefile build/flash workflow, and MCU-family context.
Hardware source tree preserving Community, Guest, Speaker, Sponsor, Staff, and Metro add-on design material with KiCad files, board rasters, silkscreen/edge SVGs, footprints, STEP models, and manufacturing outputs.
Official upstream `BADGE-BSIDES-CDMX-2025-03.png` community-badge raster retained locally as the image source and served as an optimized WebP delivery asset under the repository's hardware-license statement.
Official agenda source preserving the BSides CDMX 2025 schedule page and event edition context.
