BugCON 2023 Badge

Resistance-themed ESP32-S3 and RP2040 official badge

BugCON 2023's Electronic Cats repository documents the official resistance-themed BugCON 2023 badge with an ESP32S3 or RP2040 platform statement, UART, Bluetooth and Wi-Fi on ESP32S3, AA battery support, public Arduino firmware, GPL-3.0 software licensing, CERN-OHL v1.2 hardware licensing, and KiCad hardware source.

Why It Mattered

It closes a documented gap between the 2022 RP2040 BugCON badge and the 2024 ESP32-C6 line, showing the Mexican BugCON lineage experimenting with dual ESP32-S3/RP2040 firmware targets, web/terminal behavior, Bluetooth spoofing experiments, and public hardware archives.

Hardware

The README lists ESP32S3 or RP2040, UART, Bluetooth and Wi-Fi on ESP32S3, and AA batteries. The ESP32-S3 KiCad schematic preserves ESP32-S3-WROOM, USB-C, 128x32 0.91-inch I2C SSD1306 OLED, WS2812B Mini LEDs, buttons, slide switch, I2C labels, and battery rail evidence. The second hardware tree is named SAMD11 but its schematic symbol and properties identify an RP2040 design with USB-C, W25Q flash, battery cell, SSD1306 OLED, WS2812B Mini LEDs, and switches.

Software & Apps

The firmware developer guide documents Arduino library dependencies, RP2040 and ESP32-S3 board setup, I2C pin edits, production pin changes, and compile/flash targets for `rp2040` and `esp32s3`. The Badge firmware includes Wi-Fi access-point/server behavior, terminal mode, menu code, web assets, NeoPixel control, AirTag and UART modules; separate DinoGame and Spoof sketches preserve an OLED dino game and BLE advertising experiment.

Lore

The README calls it the BugCON 2023 resistance badge, uses the #unetealaresistencia hashtag, identifies Electronic Cats as designer for BugCON 2023, and keeps Electronic Cats and BugCON trademark language separate from open hardware and software licensing.

Operational history

Issues & Camp Impact

event and firmware inventory caveat note

The repository proves the official BugCON 2023 badge and preserves firmware examples, but this pass did not recover a stable official BugCON 2023 event page, venue/date source, distribution count, release binary, final flashed image, or complete audit of every generated web asset and sketch dependency.

Event and software claims stay bounded to the repository, README, developer guide, visible source tree, and decoded representative files instead of inventing event logistics or treating the repository as a fully inventoried production archive.

Confidence: repository metadata and decoded source files
Status: needs archive/event-page recovery
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-BugCON2023 repository metadata, README, firmware/readme.md, firmware tree, and current BugCON site recheck.

hardware variant evidence caveat note

The README describes ESP32S3 or RP2040, the tree exposes an ESP32-S3 KiCad design, and the second hardware path is named SAMD11 even though its schematic symbol and properties identify RP2040 hardware.

Hardware claims stay tied to visible source files rather than inferring which variant shipped, how many boards were produced, or whether every tree name matches the final production board identity.

Confidence: README and repository tree
Status: documented with caution
Timeframe: current catalogue build
Source note: BugCON 2023 README, ESP32-S3 schematic, SAMD11-named RP2040 schematic, and repository tree.

license scope caveat note

GitHub detects GPL-3.0 for the repository, while the README and LICENSE_HARDWARE.md state that hardware documentation is under CERN Open Hardware Licence v1.2 and that Electronic Cats and BugCON trademarks are not granted for PCB sales.

The catalogue can cite GPL software and CERN-OHL hardware documentation while avoiding assumptions that firmware, photos, logos, screenshots, KiCad renders, trademarks, or other media all share one reuse scope.

Confidence: GitHub API, repository README, and license files
Status: documented
Timeframe: current catalogue build
Source note: ElectronicCats/Badge-BugCON2023 README, LICENSE, LICENSE_HARDWARE.md, and GitHub API metadata.

missing rights-cleared image note

No BugCON 2023 badge image is published because the README logo, repository image files, firmware web assets, KiCad/svg2shenzhen graphics, and hardware-source render candidates 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 logos, screenshots, GitHub assets, KiCad outputs, event graphics, social photos, 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 and ElectronicCats/Badge-BugCON2023 repository.
