Jardin Americana, Guadalajara, Jalisco · Mexico · 2025
HackGDL 2025's official Electronic Cats event badge was an ESP32-S3 Minino-platform badge with BLE, Wi-Fi, USB-C, four buttons, three NeoPixels, an OLED screen, buzzer, three-AAA battery holder, SAO connector, case, and ready-to-use badge apps.
Lifecycle
The repository and store page say the badge ships with BLE apps, Wi-Fi apps, and a digital-pet app as ready-to-use examples for the event.
The README and store page document HackGDL 2025 as an ESP32-S3 badge based on the Minino platform.
Public badge documentation lists an integrated OLED screen, four physical buttons, three NeoPixels, buzzer, three-AAA battery holder, USB-C, and Shitty Addon connector.
The badge README points developers to the Minino firmware guide for ESP-IDF setup, modular app structure, compile, flash, and monitor workflows.
The README documents bootloader mode, ESP Tool web flashing at address 0x0, and an esptool.py console command for `HackGDL_2025.bin` on ESP32-S3.
Operational history
Software claims stay tied to the README, release path, and Minino documentation rather than treating the repository as a fully inventoried final production archive.
The catalogue can cite the source and hardware release while keeping image publication and trademark reuse separate from code and hardware licensing.
The entry remains source-backed and image-free rather than copying product photos, repository screenshots, GitHub attachments, logos, or generated imagery without complete provenance.
