Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The record documents the available hardware surfaces without endorsing RF transmission, replay, credential use, or unreviewed expansion hardware.
Evidence
Organizer-linked public repository describing the ESP32-S3 badge, KiCad sources, manufacturing outputs, hardware and software source layout, licensing boundary, and community-driven firmware path.
Primary organizer source for the June 2026 Chicago Year Two festival, its hardware and cybersecurity context, accepted-attendee hardware-badge statement, soldering-completion wording, high-level ESP32-S3/radio options, and the organizer-controlled GitHub link.
Primary guide for the ESP-IDF v5.5.x and Arduino-core source environment, USB serial flashing, automatic reset, manual recovery, and source-tree scope.
Detailed primary hardware documentation for the ESP32-S3 N8R8 module, CH340C, secure element, button matrix, display socket, side ports, power rails, and fabrication outputs.
Primary documentation for the CC1101 Sub-GHz and sound modules, shared GPIO/mutual-exclusion boundary, supported radio bands, and authoring a new module.
Organizer-linked GitHub organization profile whose listed public oniondao-badge repository ties the festival site to the technical source trail.
Source trail
Primary organizer source for the June 2026 Chicago builder-festival context, four hardware/AI/cybersecurity/blockchain weeks, accepted-attendee hardware badge, final soldering step, high-level ESP32-S3/radio statements, and official repository link.
Primary hardware source for the processor/memory, USB and boot path, power rails, I2C devices, display socket, buttons, secure element, expansion ports, and fabrication-output claims.
Primary project README for the ESP32-S3-WROOM-1-N8R8, board/source layout, display socket, secure element, I2C button expander, side ports, hardware and software licensing language, and community firmware path.
Primary source for CC1101 and sound-module hardware, shared-GPIO and mutual-exclusion behavior, radio-band boundary, and authorization wording for example use cases.
Organizer-linked source-publisher profile that lists the public oniondao-badge repository. It corroborates the relationship between the official festival site and the technical source tree, not an individual maker attribution.
Primary source for ESP-IDF v5.5.x and Arduino-core build guidance, target/memory configuration, UART flashing, automatic reset, and BOOT/RESET recovery. It does not identify a final event firmware image or every attendee's firmware state.
