REcon
The June 19-21, 2026 Montreal reverse-engineering conference whose official sponsors page names Electronic Cats as the electronic badge sponsor and whose public badge-recon-2026 repository documents a CH32V203 and RP2040 badge with LoRa, NFC, and magspoof challenges.
Hilton Double Tree Montreal, Montreal · Canada · 2026
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.
Lifecycle
The PN7150 NFC daughterboard supports tag and reader detection, Mifare Classic read and write, and a flag-hunt where tapping a tag unlocks a flag and broadcasts it to every nearby badge.
The badge emulates magnetic stripe cards over USB serial and includes a solo Simon Says memory game triggered by holding button 4.
A USB serial console enumerating as RECON2026 exposes commands for ping, mode, LEDs, LoRa transmit, chat, stats, beacon, scan, lock, Simon, reset, and test injectors.
The release notes document a 915 MHz badge-to-badge LoRa social layer with Radar discovery, Chat, and Flags sharing over the SX1262 radio.
Operational history
The catalogue records the full hardware and challenge surface without asserting the exact populated OLED variant or the physical distribution scope.
The Canadian record remains source-backed and image-free rather than copying repository diagrams, screenshots, social media, placeholders, or generated approximations.
