maker-described power and compatibility surface
The maker says the canary can run from the SAO connector or an included CR2032 battery. Its v1.0 note says hardware I2C was disconnected from the SAO connector and separate lines were used to reduce the chance of sensor-bus collisions. It does not identify voltage/current limits, battery runtime, connector pinout, I2C electrical characteristics, multi-device test data, or universal host compatibility.

first-hand Lepi Labs announcement
First-person Lepi Labs announcement naming the Volatile Organic Canary and its SGP40/display/RGB surface for DEF CON 34, plus planned Friday 12:30 PM and Saturday 2:30 PM BadgeLife Village drops. Reddit media is not a reusable image grant.

first-party Lepi Labs product listing
Lepi Labs' live Uberflux page names the DEF CON 34 drop, current $45 / 11-sold / zero-remaining state, sensor/display/controller/power claims, explicit novelty-only accuracy warning, VOC-index warmup statement, v1.0 revision notes, and remedy wording. Its product image has no stated reusable license or explicit permission basis.

maker-owned hardware and firmware source
Lepi Labs' public repository is named 5-dc34-canary-badge and contains a KiCad board/schematic tree plus a PlatformIO Arduino source tree whose SGP40, SHT4x, ATtiny1616, display, CR2032, SAO, and UPDI references align with the maker's Canary listing. The product page does not directly link the repository, so it is retained as a maker-owned matching source trail rather than proof of final v1.0 or event-unit parity. No root license file was recovered.

First-hand maker announcement corroborating the named product, SGP40 VOC-sensor, two-character display, RGB LED, DEF CON 34 association, and scheduled BadgeLife Village drops. It is not a technical release, calibration record, final stock ledger, delivery report, or image license.

Public maker-owned source archive named for a DC34 Canary. Its KiCad and PlatformIO trees contain components and software-family references matching the first-party Canary listing, but the maker's product and announcement do not directly link a revision to the event artifact. It is source context, not a final firmware, production, delivery, calibration, support, or image-rights record.
