Why It Mattered

It adds a Spanish-language DEF CON village/community badge to the North American map and preserves a useful evidence boundary around source discrepancies, licensing, and image reuse rather than treating the repository media as automatically publishable.

Hardware

The top-level README lists CH32V003, NRF24L01, Display OLED, a two-AAA battery holder, and Shitty Addon connector. The hardware tree preserves KiCad board, schematic, project, footprint, 3D, SVG/DXF, and KiBot outputs, while the firmware README and footprint names also expose a Puya PY32F002/PY32F002AA15M trail.

Software & Apps

The repository ships pre-installed firmware guidance, a v1.0.0 release asset named VillaHacker.hex, and a firmware README describing a Puya PY32F002A / PY32F002Ax5 workflow with J-Link, GNU Arm Embedded Toolchain, Make, and VSCode. The source tree includes C firmware with GPIO/LED behavior.

Lore

The official site frames La Villa Hacker as the Spanish-language village and gives August 8-10, 2025 dates. Electronic Cats is named as the badge designer in the public README.

Operational history

Issues & Camp Impact

MCU evidence discrepancy note

The top-level README lists CH32V003, while the firmware README and hardware footprint trail expose Puya PY32F002/PY32F002AA15M details.

The badge record keeps those statements source-specific and avoids claiming a single verified final controller until the project publishes a reconciled BOM or final schematic note.

Confidence: source discrepancy
Status: documented
Timeframe: current source trail
Source note: Top-level README, firmware README, and hardware tree.

distribution-scope caveat note

The official event site and Electronic Cats repository prove event and badge-project context, but this pass did not recover a static official product page proving attendee-wide distribution, final sales count, or exact pickup logistics.

The catalogue treats the artifact as a source-backed La Villa Hacker 2025 badge without implying every village attendee received one.

Confidence: source-limited
Status: open
Timeframe: La Villa Hacker 2025
Source note: La Villa Hacker site, dynamic store surface, and Badge-Villa-Hacker repository.

license-scope caveat note

The README states that the hardware is released under CERN Open Hardware Licence v1.2, while repository metadata did not expose a recognized top-level license during this pass.

The repository is used as evidence for badge facts, but no repository image or media asset is promoted into the public image archive.

Confidence: README plus GitHub metadata
Status: open
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-Villa-Hacker README and GitHub repository metadata.

missing rights-cleared image note

No La Villa Hacker badge image is published because the official site, store, and repository media have not been paired with complete reusable image license or explicit permission basis, attribution, source URL, and processing notes.

The record remains source-backed and image-free rather than copying site media, repository screenshots, renders, social-media photos, or generated replacements.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy, La Villa Hacker site/store, and Electronic Cats repository source audit.
