Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The documentation describes a Game Boy-like badge layout with OLED display and six push buttons for attendee interaction.
Badge context
Primary documentation source for ESP32-C3 WROOM, OLED, four WS2812 smart LEDs, six buttons, AA-cell case support, Arduino IDE or ESP-IDF programming, JLCPCB production-file use, and the D9 erratum.
Public source repository for the Hackbat DEF CON 32 badge, including KiCad material, documentation images, production-file workflow, and source publication context.
Official repository `doc/3d.png` raster render retained locally as the image source and served as an optimized WebP delivery asset.
Repository license source for GPL-3.0 reuse basis used by this catalogue for the upstream 3D badge render.
Hackaday.io project source stating that the Hackbat Badge was designed specially for DEFCON32 and summarizing the ESP32-C3, Wi-Fi/Bluetooth, LEDs, OLED, and first-run D9 diode warning.
Source trail
Primary hardware documentation source for ESP32-C3 WROOM, OLED, WS2812 LEDs, buttons, AA-cell case, programming options, production-file workflow, and the fixed-revision note.
Repository source for the open hardware/source tree, documentation images, KiCad/production files, and upstream 3D render.
GPL-3.0 license source supporting local publication of the official upstream repository render with attribution and source preservation.
Project-owner source describing the Hackbat Badge as designed specially for DEFCON32 and warning DEF CON recipients about the D9 diode placement issue.
