hardware API surface

RGB LED, IR, buzzer, and screen APIs

Badge.Team preserved MicroPython examples for outline RGB LEDs, buttons, power saving, buzzer tones, screen rotation, raw touch reads, and virtual timers; the hardware also exposed infrared transmit and receive.

Issues & Camp Impact

Disobey 2019 Badge note

event-network dependency · primary docs · historical

The first boot expected the event WiFi named 'badge' with credentials hardcoded into firmware; missing that window required manual reflashing for post-event configuration.

Post-event use depended on either successful event-time setup or manual reflashing.

Disobey 2019 Badge note

firmware drift caveat · primary docs · documented caveat

The programming API section says its hardware examples match the firmware flashed before and during Disobey 2019, and could have changed if the badge was later flashed with updated Badge.Team MicroPython.

The compendium should treat the preserved API examples as historical firmware behavior, not a guarantee for every reflashed device.

Disobey 2019 Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No Disobey 2019 badge image is published because the current Badge.Team source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The Finnish record remains source-backed and image-free rather than copying Badge.Team page media, documentation screenshots, event photos, placeholders, or generated approximations.
