HITCON 2025 PCB Badge

Taiwanese hacker-pet PCB badge with Red-vs-Blue tower play

HITCON 2025's official PCB Badge guide and public technical repository document an attendee PCB badge with a hacker-pet mode, built-in games, pedometer scoring, cross-board interaction, BadUSB behavior, Red-vs-Blue tower-capture play, and released STM32CubeIDE-oriented firmware/PCB project materials.

Why It Mattered

It extends the HITCON lineage from 2024's PCB badge into a richer physical-game platform where the badge linked personal play, sponsor interactions, walking, badge-to-badge connection, BadUSB scripting, and a team territory game.

Hardware

The official guide proves a physical PCB badge with buttons, a display surface for names/scores/pet state, an infrared transmission role in tower capture, a cross-board connector for badge-to-badge game battles, USB behavior, and a shown badge ID workflow. The public repository adds hardware-version context for V1.1 2024 attendee hardware, V2.0/V2.1 2025 prototypes, and V2.2 2025 attendee hardware, plus firmware pin/timer notes for IR TX/RX, LED row/column refresh, buttons, and cross-board USART. Its production CSV identifies an STM32F103CBT6 LQFP-48 controller, a DEALON USB-TYPE-C-018 connector, eight TL3301-style buttons, an IRM-H638T IR receiver, LSM6DS3TR-C motion sensor, AAA battery holder, 128 0402 LED positions, and related regulator/oscillator/transistor parts. This pass still avoids unsupported shipped-count or rights-cleared image claims.

Software & Apps

The guide documents name editing, display modes, brightness control, score display, Hacker Pet health/level behavior, Tetris, Dino, Snake, Re:CTF badge-ID binding, BadUSB script loading/execution, and cross-board game battle flows. The repository documents an STM32CubeIDE firmware workflow, hardware build configurations, a menu flow with single-player and two-player applications, and lower-level BadUSB HID write protocol notes.

Lore

HITCON's Red-vs-Blue activity randomly assigned attendees to teams using badge light color, then turned the venue into a physical CTF where badges earned points through movement, games, pet battles, challenges, and tower interactions.
