Buenos Aires speaker VIP identity badge
A conservative NotPinkCon 2019 record for the VIP badge listed as a speaker benefit in the conference CFP, tied to the Buenos Aires women-led information-security conference rather than an electronic badge lineage.
Official role and competition badge-art variants

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.
Announced exclusive electronic badge in elapsed five-day offensive-security diploma package
DragonJARCON's current official 2026 page advertises an exclusive electronic badge only as a benefit of its five-day in-person Offensive Security Diploma, scheduled in Medellín for September 14-18 and including entry to the September 10-11 DragonJAR Security Conference. The conference and diploma dates have elapsed: the official home now marks the 2026 congress as a past event and pivots registration to 2027, while the rechecked diploma page still reads as a pre-event sales listing. This source-backed record preserves the announced, package-scoped electronic-badge claim without asserting delivery.
Champion-tier nRF52840 LoRa Meshtastic badge
The Ekoparty 2026 electronic badge, included with the Champion ticket tier while supplies last. On October 3, 2026, four days before the October 7-9 Buenos Aires conference, badge-team member Nicolas Restbergs (Fábrica Marciana) published the ekoparty-badge-2026 repository, which calls itself the firmware for the official Ekoparty 2026 badge: a Meshtastic node on an nRF52840 with an SX1262 LoRa radio, a 0.96-inch OLED, Bluetooth pairing with the Meshtastic phone app, a piezo buzzer, six rear SK6812 backlight pixels, and a separate status pixel. The release v1.0.3 adds a schematic, pin map, user manual, and the EKOBOOT bootloader image; v1.0.4 followed on October 5, and an EasyEDA Pro project and a low-temperature-solder fragility warning were added on October 8, during the conference. By October 9, 2026 Ekoparty's own event page carried an EKO BADGE ELECTRÓNICO section describing the badge as a customized Meshtastic build that works off-grid and links to the badge team's guide, and an October 12 attendee writeup confirms the event took place with Meshtastic Eko Badges in hand. Production count and allocation stay unconfirmed.
CH573F BLE virtual-pet and CTF electronic badge
A source-backed Peruvian Unknown Security Conference 2026 electronic-badge record that joins the official pass's lanyard-and-badge inclusion with Electronic Cats' self-described official Pwn Llama badge repository. Its public history shows hardware work before the June 4-6 Lima event and a July documentation update.
