CONFidence
The May 25-26, 2026 CONFidence cybersecurity conference in Krakow, whose official badge site documents the hackable electronic ConfiBadge with ESP32-C6, OLED, audio, controls, expansion hardware, Badge Hub, and media/showcase context.
EXPO Krakow, Krakow · Poland · 2026
An official electronic badge for CONFidence 2026 in Krakow, documented as a hackable ESP32-C6 platform with OLED display, I2S audio amplifier, six navigation buttons, rechargeable LiPo power, firmware challenges, an 8-pin expansion port, and a live Badge Hub for MicroPython packages and community mods.
Lifecycle
The hardware page lists a MAX98357AETE+T I2S amplifier and onboard speaker as the badge's audio path.
The badge is documented with a 128x64 SH1106-driver OLED and six navigation buttons for direct interaction.
The badge page describes an 8-pin expansion header exposing GPIO for custom daughterboards and mods.
The official media page points to a main showcase video and making-of material for the ConfiBadge 2026.
The hardware page lists ESP32-C6-WROOM-1-N8 with Wi-Fi 6, BLE 5, and Zigbee/Thread as the badge's core SoC.
The pinout page lists button GPIOs, OLED I2C pins, I2S/audio labels, and userport GPIOs for badge hacking, with the exact table kept as documentation rather than a schematic or PCB archive.
The badge home page invites attendees to explore firmware, write code, use onboard peripherals, and discover hidden features and challenges.
The official Badge Hub page says ConfiBadge 2026 software, MicroPython libraries, example apps, and community-contributed mods live in the hub.
Operational history
The record keeps the electronic badge separate from ordinary conference-ID logistics and does not assume every ticket tier receives the ConfiBadge unless distribution details are explicit.
The Poland badge record remains image-free rather than copying site imagery without explicit reuse rights.
The catalogue records the pinout as a hacking reference while avoiding manufacturing-grade claims until final design files appear.
Hardware claims stay limited to the official component list and pinout table, and software claims stay limited to the official Badge Hub, package-hub, and stated firmware/challenge goals.
The record can document the software hub without overstating it as a full production archive.
