BugCON 2025 Linux Badge

RV1106 Linux badge with add-on and embedded-Linux hacking path

BugCON 2025's Electronic Cats badge repository documents an open-hardware RV1106G3 Linux badge with ARM Cortex-A7, RISC-V MCU, NPU, ISP, GPIO, MIPI CSI, UART, SPI, I2C, USB hub, Ethernet path, WS2812E NeoPixels, 18650 battery support, Python scripting, and a PY32F002 add-on board.

Why It Mattered

It extends the Mexican BugCON lineage beyond the ESP32-C6 2024 badge into a Linux-capable badge platform, preserving a public hardware tree, release-image workflow, and attendee-facing debug and scripting documentation for Latin American badge hacking.

Hardware

The README lists an RV1106G3 main badge core with ARM Cortex-A7, RISC-V MCU, NPU, ISP, Linux support, GPIO, MIPI CSI, UART, SPI, I2C, USB, GPIO-based Ethernet, WS2812E NeoPixels, 18650 battery support, buck conversion, and USB-A. The project tree also preserves KiCad main-badge schematics and board files plus a PY32F002AA15M add-on board with decorative artwork and firmware material.

Software & Apps

The README documents 3.3 V TTL debug serial on UART2 at 115200 baud, root login with the published event password, Python 3.11.6 on the badge, spidev NeoPixel control examples, Luckfox/Rockchip Buildroot and device-tree paths, USB host configuration, and release-image flashing with `upgrade_tool` and `Bugcon-Badge-2025-v1.0.img` / v1.1 tarballs.

Lore

BugCON's CFP frames the November 20-21, 2025 Mexico City event as a long-running technical security conference, while the current BugCON site preserves the 2025 event identity, ticketing, Fronton Bucareli venue map, and participation-certificate flow. The badge README calls it Electronic Cats' first embedded-Linux badge for BugCON.

Issues & Camp Impact

license scope caveat note

GitHub reports no detected top-level license for `ElectronicCats/badge-bugcon-2025`, and the README says to consult license files without exposing a simple whole-repository license for hardware, firmware, photos, diagrams, or artwork.

The catalogue can cite the open-hardware claim and public source while avoiding assumptions that firmware, SDK material, readme images, KiCad renders, logos, or event graphics are reusable publication assets.

Confidence: GitHub API, repository tree, and README
Status: documented with caution
Timeframe: current catalogue build
Source note: ElectronicCats/badge-bugcon-2025 repository metadata, README, and badge.gallery image policy.

missing rights-cleared image note

No BugCON 2025 badge image is published because the repository readme images, diagrams, KiCad/svg2shenzhen rasters, event-site graphics, and sponsor or ticketing artwork have not been paired with complete reusable image rights, attribution, source URL, and processing provenance for catalogue publication.

The entry remains source-backed and image-free rather than copying diagrams, screenshots, event artwork, GitHub assets, logos, or generated imagery without complete provenance.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy, BugCON 2025 event site, and ElectronicCats/badge-bugcon-2025 repository.

release and source inventory note

The README and releases document v1.0/v1.1 image tarballs, add-on firmware hex, BOM asset names, and the Luckfox SDK branch, but this pass did not audit every large release image, generated SDK artifact, dependency license, or manufacturing output.

Software and production claims stay tied to README, release names, public hardware trees, and the named SDK branch rather than treating the repository as a fully inventoried production archive.

Confidence: repository documentation
Status: needs deeper artifact inventory
Timeframe: current catalogue build
Source note: ElectronicCats/badge-bugcon-2025 README, releases page, hardware trees, and SDK branch.
