BSides SP 2026 Garoa Badge REV. 0
Garoa ESP8266/OLED community electronic badge
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.
