BSides Vilnius 2026 Badge

Lithuanian STM32H5 electronic badge with SAO and sensor

An official Lithuanian Security BSides 2026 electronic badge documented by the BSides-Vilnius badge2026 repository as an STM32H563RIT6 board with an SAO connector, an environmental temperature/humidity sensor, an LCD, and USB DFU, built for the June 3-4, 2026 event at Kablys in Vilnius.

Why It Mattered

It adds Lithuania to the European badge map as a new country with an organ-owned, BSD-2-Clause-licensed repository and a primary-source MCU identification, while keeping display, button, and designer detail withheld until stronger sources appear.

Hardware

The official repository's STM32Cube .ioc file identifies the microcontroller as an STM32H563RIT6 and the firmware exposes an SAO connector, an onboard temperature/humidity environmental sensor, an LCD, and USB Device Firmware Upgrade support. The exact LCD part and resolution, button count and layout, power source, and any wireless radio are not identified in the recovered sources, so this record does not invent those details.

Software & Apps

The BSides-Vilnius/badge2026 repository is published under a BSD-2-Clause license and preserves the badge firmware and STM32Cube configuration, but the recovered sources do not document a badge challenge, CTF integration, or app surface beyond the LCD, SAO animation, environmental sensing, LED sparkle, and USB CDC threads visible in the firmware.

Lore

BSides Vilnius is the Lithuanian Security BSides chapter, and the 2026 edition ran June 3-4 at Kablys on Kauno gatve 5 in Vilnius. The badge repository's file paths reference Vytautas Krakauskas, but the public sources do not name a badge designer or team explicitly, so the designer attribution stays inferential rather than official.

Issues & Camp Impact

designer attribution note

The repository file paths reference Vytautas Krakauskas, but the public sources do not name a badge designer or team explicitly.

The designer attribution stays inferential from file paths rather than an official credit until BSides Vilnius names the badge team.

Confidence: inferential from repository file paths
Status: unconfirmed
Timeframe: current catalogue build
Source note: BSides-Vilnius/badge2026 repository file paths.

hardware-detail gap note

The repository identifies the STM32H563RIT6 MCU, SAO connector, environmental sensor, LCD, and USB DFU, but the exact LCD part and resolution, button count and layout, power source, and any wireless radio are not identified in the recovered sources.

The catalogue records the verified hardware surface without inventing component-level display, input, power, or radio details.

Confidence: official repository but incomplete
Status: needs deeper archive recovery
Timeframe: 2026 badge archive pass
Source note: BSides-Vilnius/badge2026 repository .ioc file and firmware threads.

missing rights-cleared image note

No BSides Vilnius 2026 badge image is published because the repository does not pair a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The Lithuanian record remains source-backed and image-free rather than copying repository diagrams, documentation screenshots, social media, placeholders, or generated approximations.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and BSides-Vilnius/badge2026 repository.
