REcon 2026 Badge

Montreal CH32V203 and RP2040 badge by Electronic Cats with LoRa and NFC

A Canadian REcon 2026 official electronic badge by Electronic Cats, documented by the official sponsors page and the public badge-recon-2026 repository as a CH32V203 primary board with an RP2040 daughterboard, an SSD1306 OLED, a Semtech SX1262 915 MHz LoRa radio, an NFC PN7150 daughterboard, four buttons, USB-C, and a rich LoRa radar, chat, flag, NFC flag-hunt, magspoof, and Simon challenge surface.

Why It Mattered

It adds the standalone Montreal REcon conference (distinct from the DEF CON Recon Village) to the Canadian badge map with an official sponsor confirmation, a dual-licensed AGPL-3.0 and CERN-OHL-1.2 repository with full KiCad design files, a named designer, and a richly documented challenge surface, while keeping the final OLED variant and distribution scope withheld.

Hardware

The badge uses a CH32V203 primary microcontroller, an RP2040 daughterboard carrying the SSD1306 OLED display and PN7150 NFC, a Semtech SX1262 915 MHz LoRa radio, four push buttons, and USB-C power, per the ElectronicCats/badge-recon-2026 repository, which includes a complete KiCad hardware project under CERN-OHL-1.2. The exact populated OLED variant (128x32 or 128x64) and the physical distribution scope are not confirmed in the recovered sources.

Software & Apps

The AGPL-3.0 firmware and recon2026-v1 release expose a LoRa social layer with Radar, Chat, and Flags over 915 MHz, an NFC flag-hunt that broadcasts a tapped flag to every nearby badge, magspoof magnetic-stripe emulation, a Simon Says solo game, per-button RGB LED control, a USB serial CLI enumerating as RECON2026, a hidden reversing challenge, and a Konami-code easter egg carried from the 2025 badge.

Lore

REcon is a premier reverse-engineering and security conference held annually in Montreal since 2005, and the 2026 edition ran June 19-21 with training June 15-18 at the Hilton Double Tree Montreal. The official sponsors page names Electronic Cats as the electronic badge sponsor, and the public repository credits DeimosHall (Francisco Torres) as lead developer.

Issues & Camp Impact

OLED variant and distribution gap note

The repository carries two SSD1306 OLED footprint variants (128x32 and 128x64) and does not confirm which is populated on the final badge, nor whether the badge was distributed to all attendees or a limited quantity.

The catalogue records the full hardware and challenge surface without asserting the exact populated OLED variant or the physical distribution scope.

missing rights-cleared image note

No REcon 2026 badge image is published because no reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes has been recovered.

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