Robotic Hacking Community DEF CON 34 AI-Connected Badge
Post-event STM32U073 badge with MIT firmware, AI control, and CTF surface
A post-event official RHC firmware release documents the AI-Connected DEF CON 34 badge as an STM32U073 device with a 1.54-inch 200×200 e-paper display, two WS2812 eyes, arm LED, buzzer, vibration motor, NEC infrared, CH340 USB serial, four buttons, on-badge CTF challenges, and AI Interactive Mode. The MIT-licensed source and binary were published August 18-20 after the scheduled August 6-9 Las Vegas programme. This establishes a released badge platform, not a recipient count, individual pickup, or a complete production ledger.
