Car Hacking Village DEF CON 34 CAN-FD CTF Badge
RP2040 CAN/CAN FD vehicle-network CTF badge, with post-event fulfillment unverified
Car Hacking Village publicly announced its DEF CON 34 CTF badge. Official Village posts identify an RP2040, DB9 CAN 2.0/CAN FD support, interactive power management, and a 12 V 1.5 A power supply; the public `chv_badgetools` repository identifies itself as host-side CAN utilities for the DEF CON 34 badge. The scheduled August 6-9 Las Vegas event window has elapsed, but reviewed post-date sources still do not prove final badge manufacture, allocation, handoff, CTF operation, or a released final firmware.

Why It Mattered
It extends the Car Hacking Village lineage with a CTF hardware platform whose public host tooling makes its CAN workflow concrete. The entry separates explicit engineering and announced on-site CTF claims from unverified details about final board design, firmware, quantities, variants, recipient scope, delivery, and event outcomes.
Hardware
An official Car Hacking Village announcement lists DB9 CAN 2.0/CAN FD support, interactive power management, a 12 V 1.5 A power supply, and an RP2040. The public tooling README says the badge connects over USB, its detection path uses an RP2040 USB vendor ID, and it supports CAN FD frames up to 64-byte payloads with a default 500 kbit/s CAN bitrate. The reviewed sources do not identify the RP2040 board variant, CAN transceiver part(s), physical bus count, USB bridge details, battery/power-source arrangement, LED/display/input hardware, PCB layout, schematic, BOM, Gerbers, production run, or final physical variants.
Software & Apps
The public `chv_badgetools` repository provides Python 3.8+ host tools: `chv-candump`, `chv-cansend`, automatic port discovery, and a `python-can` interface plugin for macOS and Linux. It documents USB serial paths, CAN/CAN FD monitoring and transmission, and `python-can` integrations. It is host-side tooling, not a full released badge-firmware or hardware-design archive, so this record does not claim final firmware, source completeness, flashing instructions, or a license for the badge itself.
Lore
Car Hacking Village's official CTF announcement says all DEF CON 34 challenges would be on-premise with no remote component. It says tools would be available through Ethernet/USB or by purchasing the CHV main badge, and that five CHV badges would be available for CTF participants, so purchase was not stated as necessary to compete. These announced logistics are not proof of final badge delivery, a universal attendee issue, CTF execution, or final rules.

On-premise CTF badge access
The pre-event CTF announcement says all challenges would be on-premise, purchase would not be necessary to compete, and five CHV badges would be available specifically to CTF participants. The scheduled event dates have elapsed, but final allocation and CTF operation remain unreported.

allocation and CTF-access boundary
note
The official pre-event CTF announcement says a badge could be purchased from the Village and five CHV badges would be available specifically for CTF participants, while also saying purchase was not necessary to compete. It does not publish a final sales quantity, recipient population, allocation process, physical variant list, CTF result, or final rules.
The catalogue does not infer universal distribution, a guaranteed participant badge, a completed CTF, or a final allocation count from the announced CTF access route.

hardware and firmware documentation gap
note
Public sources establish high-level RP2040, CAN/CAN FD, power, USB, and host-tool behavior but do not provide a complete badge board design, schematic, BOM, Gerbers, transceiver details, power source, manufacturing files, main firmware, flashing workflow, or final badge-specific license.
The record retains documented engineering surfaces while withholding a complete implementation claim until Car Hacking Village publishes a final technical archive.

missing rights-cleared image
note
No Car Hacking Village DEF CON 34 badge image is published because the official event site, official announcements, and public repository do not pair a specific badge image with source URL, reusable license or explicit permission basis, attribution, and processing notes.
The United States record remains source-backed and image-free rather than copying event-site artwork, LinkedIn images, repository previews, screenshots, placeholders, or generated approximations.

post-event fulfillment boundary
note
Car Hacking Village announced an August 2026 DEF CON 34 badge and CTF. Its official event listing remains public after the August 6-9 scheduled window, but reviewed primary sources do not report final badge manufacture, allocation, handoff, completed CTF operation, production, or an attendee-wide issue.
The catalogue preserves a documented hardware project and host tooling without converting a lapsed schedule into a fulfilled-badge, completed-CTF, or delivery claim.
