BSides SP

BSides SP 2026

The completed May 16-17, 2026 Security BSides SP V21 edition in São Paulo. Garoa Hacker Clube's public event, REV. 0 hardware, and demo sources associate an ESP8266 Garoa badge with this conference while leaving the exact 2026 firmware, allocation, and final hardware-revision mapping unresolved.

BSides SP 2026 Garoa Badge REV. 0

Garoa Hacker Clube's own event-period demo repository identifies its REV. 0 board as a badge distributed at BSides SP 2026. The Garoa and official V21 event sources establish the completed São Paulo conference, while the public source trail documents an ESP8266 badge with a 128×64 OLED, buttons, sound/IR path, microSD socket, FTDI programming header, and public KiCad/Gerber/BOM material. It does not prove one final firmware or hardware revision for every conference unit.

Add-ons & Upgrades

BSides SP 2026 Garoa Badge REV. 0 source-backed but experimental

firmware demo archive

Alpha MicroPython conference demo

Garoa’s event-period demo archive is a MicroPython, one-app-per-flash collection associated with BSides SP 2026 and explicitly labeled alpha/experimental. It is recorded as an archival software surface rather than a verified on-badge deployment.

hardware architecture

ESP8266/OLED board core

Garoa’s REV. 0 documentation identifies an ESP8266, a 128×64 OLED, three GPIO buttons plus Reset, and a buzzer/IR path. It does not establish a complete final component population for every 2026 unit.

hardware source archive

KiCad, BOM, and Gerber archive

The commit-pinned Garoa hardware tree preserves KiCad, BOM, and Gerber material for the platform. Its cross-year source history does not map a particular tree state to every distributed 2026 board.

storage and programming interface

MicroSD and FTDI service interfaces

The REV. 0 documentation identifies a microSD socket and FTDI programming socket as physical interfaces. The catalogue records their presence without asserting media contents, production wiring, service policy, safety, or support outcomes.

Issues & Camp Impact

BSides SP 2026 Garoa Badge REV. 0 note

REV. 0 build and revision caveat · Garoa primary hardware documentation · documented; final 2026 revision unresolved

Garoa’s REV. 0 documentation records a PCB correction/rework requirement and proposed next-revision changes. The source archive also contains an earlier BSidesSP 2025-named test path, rather than a tagged 2026 production release.

The record does not turn the documented REV. 0 platform into a claim that every 2026 badge had the same corrected board, components, physical build, or event-ready firmware.

conference deployment and allocation boundary · Garoa organization demo archive with official event corroboration · documented caveat

Garoa’s demo README says the REV. 0 badge was distributed at BSides SP 2026, but the reviewed public sources do not provide a recipient ledger, allocation criteria, production quantity, hardware-variant inventory, event-day firmware image, or source-to-unit mapping.

The catalogue records the source-backed event association without implying that every attendee received an identical unit or that the current demo archive was installed on conference hardware.

BSides SP 2026 Garoa Badge REV. 0 note

hardware source-reuse boundary · public repository metadata and reviewed root tree · needs explicit project license or permission

The Garoa wiki calls the project open hardware and its page content carries a CC BY-SA notice, but the reviewed BadgeGaroa_r2 root has no detected top-level repository license. Those facts do not establish reusable rights for all code, CAD, documentation, or images in the project tree.

The catalogue links to the technical source as evidence while withholding local copies of repository imagery, CAD, and source material until a clear reuse basis is identified.

BSides SP 2026 Garoa Badge REV. 0 note

missing rights-cleared image · local project policy · needs licensed original replacement

No BSides SP 2026 Garoa Badge REV. 0 image is published because the official event page, Garoa wiki, and public repositories do not pair a selected physical badge image or upstream raster with a reusable license or explicit permission basis, attribution, source URL, and processing provenance.

The record remains source-backed and image-free rather than copying event graphics, Garoa wiki media, repository previews, screenshots, social images, or generated approximations.
