BSidesSLC
The April 10-11, 2025 Salt Lake City Security BSides edition whose current official site documents a 2025 E-Badge built on a LilyGO T-Deck S3 with keyboard, trackball, LEDs, ESP32-S3, LoRa, Meshtastic readiness, and later 2026 pickup for remaining stock.
Conference Center at Miller Campus, Sandy, Utah · United States · 2025
The BSidesSLC 2025 E-Badge is a source-backed custom electronic badge that BSidesSLC describes with an ESP32-S3-WROOM, LoRa, 25 addressable LEDs, TFT display, Micro-USB or three-AA power, mini-badge slots, and custom Meshtastic firmware.
Lifecycle
The official hardware description lists a TFT display and 25 addressable LEDs as the documented visual interfaces.
The official site offers remaining 2025 E-Badges through 2026 ticketing and instructs buyers to pick them up at the April 2026 conference.
BSidesSLC lists Micro-USB or three-AA power, three mini-badge expansion slots, a UART point, reset and flash buttons, and a USB/battery power switch. The source does not establish final electrical limits, safe modification procedures, or every delivered configuration.
The official BSidesSLC page identifies a custom ESP32-S3-WROOM electronic badge with a LoRa module and custom Meshtastic firmware.
distinctm1nd's public archive contains matching badge documentation, KiCad PCB/schematic files, and a Meshtastic-derived source tree. The event does not directly link it, so it supports hardware and firmware discovery without proving final production or deployed software.
Operational history
Country and event pages can show the 2025 badge lineage without turning remaining-stock pickup into an unsupported new edition.
The catalogue can now record the public technical archive while withholding an audited final BOM, manufacturing package, event firmware image/configuration, app settings, challenge archive, production count, and proof that every delivered unit matched the public tree.
The entry remains source-backed and image-free rather than copying site artwork, repository renders, generated-looking imagery, ticketing media, social photos, or screenshots.
