DCZia MK9 Badge (DEF CON 34)
Pre-event RP2040 mechanical macropad BadgeLife project
DCZia's MK9 is a public-source 3×3 mechanical macropad intended as a neck-wearable DEF CON 34 BadgeLife project. Project documentation specifies nine MX switches, RGB per-key and edge lighting, an accelerometer, two 6-pin SAO connectors, USB-C or three-AAA power, CircuitPython firmware, and QMK-compatible hardware. A public August 2 announcement says the project plans BadgeLife pickup, but this remains a pre-event independent badge rather than an official DEF CON admission credential.
