MCU platform
STMicroelectronics STM32 microcontrollers power a long lineage of camp and conference badges, from the rad1o SDR badge to modern STM32H5 designs.
STM32 Hardware Hacking Village badge
Ruxcon 2015's Hardware Hacking Village badge is preserved here as an Australian STM32 badge with public KiCad/Gerber files, schematic material, firmware examples, SMD assembly instructions, CR2032 power, and SWD/OpenOCD programming notes.
STM32F030 IR Hardware Hacking Village badge
Ruxcon 2016's Hardware Hacking Village badge is preserved as an Australian STM32F030K6T6 badge with IR receiver/emitter hardware, eight LEDs, dual CR2032 holders, assembly documentation, and a public firmware archive.
Moscow STM32 serial-console badge
An OFFZONE 2026 conference badge documented through a first-hand attendee toolkit: an STM32 board with a USB Virtual COM Port exposing a built-in serial console with led, echo, and mini-game commands, four addressable LEDs driven by an official bytecode format distributed with the badge docs, and animation sequences verified byte-for-byte on real 2026 hardware.
