Utah Valley Convention Center, Provo, Utah · United States · 2018
The SAINTCON 2018 ESP32 Badge was an electronic conference badge built around a LOLIN D32 / ESP32 module running MicroPython, an 8x32 LED matrix, three buttons, a rechargeable battery, Wi-Fi configuration behavior, Hacker Challenge score display, and twelve minibadge spots.
Lifecycle
The minibadge notes define I2C address coordination plus polling, button, text, pixel, timed-pixel, custom-data, score-update, and brightness-change messages.
The badge uses an 8x32 LED matrix and three buttons to show SAINTCON, a custom message, Hacker Challenge score, Hacker Challenge ID, brightness, Wi-Fi status/configuration, and minibadge controls.
The badge README and firmware document a Wi-Fi configuration mode where the badge displays an SSID and password, then hosts a configuration flow for network settings and the custom message.
The official badge page and README document twelve minibadge spots, included female minibadge headers, and expanded minibadge support for the 2018 event.
The badge README documents an ESP32 Wi-Fi module running MicroPython, and the repository preserves the source tree and binary image used to operate the badge.
Operational history
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record preserves operational and add-on-design constraints rather than presenting the badge as a frictionless reference platform.
The catalogue cites the repository as evidence but does not republish repository media or treat design files, PDFs, or images as reusable publication assets.
