DOJOConf Panamá 2026 Electronic Badge

Limited ticket-holder CH573F badge with a public hardware archive

DOJOConf Panamá's official page advertises a limited, separately purchased electronic badge available only to ticket holders, with an integrated OLED, four physical buttons, and a rechargeable USB-C battery. An organizer-controlled update says the 2026 badge will be useful in the CTF, and an Electronic Cats post names that organization as the edition's designer and maker. Electronic Cats' public `badge-dojocon-2026` repository separately identifies itself as the official Badge DojoCon Panamá 2026 archive and has a pre-event v1.0 release. Its commit-pinned documentation records a CH573F RISC-V/BLE design with an OLED, directional buttons, a WS2812B LED, USB-C, and a battery connection. These sources establish a real event artifact and public design trail, not completed delivery or a source-to-recipient configuration mapping.

Pwnterrey 2026 Official ESP32-C5 Badge

Official open-hardware headless ESP32-C5 wireless-security badge with public KiCad and C5 firmware sources

Electronic Cats' public badge-pwnterrey-2026 repository describes itself as the official Pwnterrey 2026 badge and publishes a native KiCad hardware project plus a CERN Open Hardware Licence v1.2 file. Pwnterrey's official site places the free cybersecurity conference in Monterrey on May 29, 2026; Bishop Fox separately corroborates the date and Rincón Tostitos By Jardín 85 venue. The source documents a portable headless ESP32-C5 RISC-V badge with USB-C serial context, NFC tag-emulation circuitry, and GPS material. Electronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and preserves an ESP32-C5 Marauder-derived source and build trail. These sources establish a real official event badge and public design and firmware references, but not a production quantity, registration-tier allocation, final assembled configuration, completed recipient handoff, final signed release, safe operational use, or reusable badge-image right.

TROPICON 2026 Electronic Badge

Electronic Cats ESP32-C6 badge source with public KiCad hardware and firmware archives

Electronic Cats' public Badge_Tropicon-2026 repository describes its project as the official TROPICON 2026 badge and publishes native KiCad design material. Its commit-pinned hardware README identifies an ESP32-C6, a 2.79-inch 142×428 colour IPS display using an NV3007, LoRa hardware, and an AHT30 sensor. A companion Electronic Cats firmware archive documents software for the TROPICON badge and is marked GPL-3.0 by GitHub. The official TROPICON site establishes the completed April 17-18 Cozumel event, but does not itself link or independently confirm the technical archives, allocation, credential role, final production configuration, recipient handoff, or reusable-image rights.
