CONFidence
The May 25-26, 2026 CONFidence cybersecurity conference in Krakow, whose official site links a planned hackable electronic ConfiBadge with ESP32-C6, OLED, audio, controls, and expansion hardware.
EXPO Krakow, Krakow · Poland · 2026
A planned 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, and an 8-pin expansion port.
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 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 pre-event documentation pending post-event schematic or repository release.
The badge home page invites attendees to explore firmware, write code, use onboard peripherals, and discover hidden features and challenges.
Operational history
The record keeps the electronic badge separate from ordinary conference-ID logistics and does not assume every ticket tier receives the ConfiBadge until distribution details are public.
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 the final archive appears.
The catalogue treats the badge as planned/pre-event and should be refreshed after the conference.
Hardware claims stay limited to the official component list and pre-event pinout table, and software claims stay limited to the stated firmware and challenge goals.
