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.
