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.

Electronic Cats

Electronic Cats publishes the repository explicitly described as the official Pwnterrey 2026 badge, including the native KiCad design archive. The reviewed sources do not supply an individual contribution ledger, manufacturing record, or image-reuse grant.

event host and official badge context

Pwnterrey

Pwnterrey's official site identifies the Monterrey 2026 cybersecurity event, while Electronic Cats' repository explicitly names the badge as official for that edition. This records event context, not hardware authorship, production responsibility, attendee allocation, or media-reuse authority.

Source

source-named original firmware credit

Just Call Me Koko

The companion firmware repository's root MIT text credits Just Call Me Koko. The narrow credit preserves that source-named upstream attribution without assigning Pwnterrey badge hardware authorship, final firmware ownership, production responsibility, or image rights.

Why It Mattered

This Mexican post-event open-hardware badge dossier adds a source-backed Monterrey conference artifact with native KiCad and ESP32-C5 material. It keeps an explicit official-repository label distinct from unverified attendee allocation, production completion, final firmware parity, radio performance, safe operation, and image-reuse terms.

Hardware

The published KiCad project identifies an ESP32-C5-WROOM-1-N4, an NT3H2111W0FHK NFC tag chip, USB-C connectivity, GPS footprints and labels, and schematic, PCB, and project sources. The README calls it a portable headless ESP32-C5 RISC-V device using a serial CLI and lists Wi-Fi 6 and Bluetooth Low Energy context. The reviewed sources do not establish a BOM, PCBA, battery or charging design, antenna or final RF implementation, final revision, completed units, test results, certifications, safety details, or that every published element appeared in each assembled badge.

Software & Apps

Electronic Cats' companion repository calls itself the official Pwnterrey 2026 firmware and retains ESP32-C5, headless, Marauder-derived source and build material. Its root MIT text credits Just Call Me Koko, while the reviewed sources do not establish the license scope of every later modification, a reviewed release tag, a signed production binary, or parity between public files and distributed hardware. The materials indicate high-level wireless and NFC security-testing functions only within owner-authorized, lawful, and privacy-respecting work; this record supplies no operational instructions and makes no claim of safe default use.

Lore

Pwnterrey's official site presents the May 29, 2026 Monterrey edition as a free cybersecurity event, while Electronic Cats explicitly labels the public repository Badge Oficial de Pwnterrey 2026. Bishop Fox independently lists the date and Rincón Tostitos By Jardín 85 venue. None of the reviewed sources confirms inclusion with admission, recipient count, registration tier, price, pickup, delivery, credential role, final handoff, or a fully documented post-event outcome.

C5 Marauder-derived firmware and public build-material boundary

Electronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and retains ESP32-C5 headless Marauder-derived source, documentation, and build material. Its root MIT text credits Just Call Me Koko; this record does not equate that upstream text or visible build artifacts with a final signed event binary, production configuration, safety review, or generalized authorization to operate wireless functions.

Official 2026 Pwnterrey badge and event-context boundary

Electronic Cats describes its public hardware repository as the official Pwnterrey 2026 badge, while Pwnterrey's official site documents the free May 29 Monterrey cybersecurity-event context. Neither reviewed source confirms admission inclusion, recipient eligibility, quantity, price, pickup, delivery, completed handoff, or a credential function.

Public native KiCad schematic, PCB, and project files

The hardware repository exposes native KiCad schematic, PCB, project, footprint, and related automation material. Public source availability does not by itself establish a complete BOM, fabrication readiness, tested manufacturing output, production run, firmware parity, or reuse rights for every non-hardware asset.

Operational history

Issues & Camp Impact

event allocation, production, and fulfillment gap note

The official site establishes Pwnterrey's May 29, 2026 event and Electronic Cats labels the public hardware repository official, but reviewed sources do not state a badge quantity, admission inclusion, registration tier, price, order record, recipient ledger, pickup, delivery, completed handoff, final production count, or post-event distribution outcome.

The catalogue preserves the official design and event association without presenting the badge as universally issued, sold, delivered, accepted, or used as an admission credential.

firmware release, production parity, and source-history gap note

The companion repository contains ESP32-C5 headless Marauder-derived source, documentation, and build material and calls itself official Pwnterrey firmware, but this pass did not establish a reviewed final release tag, signed binary, reproducible event build, contribution history for every change, full dependency inventory, or parity with any distributed badge.

The catalogue records public software provenance without representing a visible build artifact as the final event firmware, an audited release, a complete source history, or an authorized deployment.

hardware, firmware, media, and trademark license boundary note

The hardware repository publishes CERN Open Hardware Licence v1.2 text for hardware documentation, while the companion firmware repository's root MIT text credits Just Call Me Koko. These findings do not automatically license all later firmware modifications, repository graphics, readme images, event media, logos, names, or trademarks.

The record links source and license material while leaving media publication, firmware-modification scope, branding, and trademark reuse outside the stated hardware-documentation basis.

missing rights-cleared image note

No Pwnterrey 2026 badge image is published because the official event pages, hardware and firmware repositories, and readme graphics do not pair a selected factual artifact image with a reusable license or explicit permission basis, attribution, source URL, and processing provenance for local publication.

The record remains source-backed and image-free rather than copying repository graphics, event visuals, screenshots, social-media images, placeholders, or generated approximations.

wireless, NFC, GPS, privacy, and lawful-use boundary note

The public materials describe Wi-Fi, Bluetooth Low Energy, NFC, GPS, and Marauder-derived security-testing context, but do not provide a complete event-use policy, operator authorization record, data-handling terms, final RF configuration, range/interference testing, regulatory documentation, or a general-purpose safe-use guide.

The dossier contains no operational instructions and does not treat source-described wireless, NFC, or GPS capabilities as permission to test third-party systems, collect data, evade privacy expectations, or operate outside lawful owner-authorized work.
