Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The record distinguishes current CircuitPython documentation and documented hardware capability from an asserted shipping QMK configuration or final delivery configuration.
Evidence
Public CircuitPython documentation covering the RP2040 pinout, key matrix, LEDs, MSA301-compatible accelerometer, SAO buses, state-machine behavior, USB HID numpad mapping, libraries, and BOOTSEL/UF2 update workflow.
Public DCZia source tree titled `dczia's defcon 34 badge for 2026`. Its README documents the 3×3 mechanical macropad, hardware/features, CircuitPython/QMK direction, KiCad/BOM/fabrication material, and update path. Public repository images are evidence only, not a reuse license.
Public August 2 announcement identifying the 2026 DCZia MK9, tying it to DEF CON 34, summarizing the hardware and public source trail, and announcing planned Friday/Saturday BadgeLife pickup. Its animated/post image does not establish reusable image rights.
Source trail
Primary public firmware source for the CircuitPython 8+ state machine, 3×3 key matrix pinout, 15 NeoPixels, MSA301-compatible accelerometer, SAO I2C/GPIO, visual behavior, USB HID numpad mapping, required libraries, and BOOTSEL/UF2 flash steps.
Primary public project source that calls the MK9 a DEF CON 34 2026 badge and documents the mechanical macropad form, nine switches, WS2812B and SK6812 LEDs, RP2040, accelerometer, SAO connectors, USB-C/AAA power, CircuitPython, QMK-compatible hardware, KiCad design files, BOM, fabrication outputs, and update path. The reviewed repository root does not expose an explicit license.
Public August 2 pre-event announcement tying the 2026 MK9 to DEF CON 34 and planned BadgeLife pickup. It corroborates the launch context and a planned add-on, but is not used as final fulfillment proof or as an image-reuse license.
