SourceICS Village at DEF CON 34 · United States · 2026
Pre-event RP2350B multi-protocol OT and automotive research badge
The ICS Village DEF CON 34 Badge is an official FREE-WILi page-documented, on-site / Vendor Village, while-supplies-last hardware badge for DEF CON 34. Its technical page specifies an RP2350B-A4 platform with RS485/Modbus RTU, CAN/CAN FD, 10BASE-T1S and 10BASE-T1L, a DB15 connector, OLED, encoder and RGB UI, storage, USB serial, FreeWili Porpoise Purpose Firmware, OneWili API support, and a stated 3.7 V / 1000 mA internal battery. As of this pre-event source pass, it is not a delivered-run or official DEF CON admission credential.
People
Publisher of the official DC34 badge documentation that names the hardware platform, firmware, and OneWili API surface.
SourcePublisher of the official ICS Village DEF CON 34 event page and Las Vegas Convention Center schedule context.
SourceIt brings the ICS Village lineage from the DEF CON 33 FREE-WILi platform into the current event record with a rare, explicitly documented convergence of legacy RS485/Modbus, automotive CAN/CAN FD, and single-pair Ethernet interfaces. The dossier records the unusually specific public specification while retaining the boundaries around source code, electrical design, safety, production, availability, and credential status.
The official badge page specifies a Raspberry Pi RP2350B-A4, RS485 with Modbus RTU capability, CAN and CAN FD, 10BASE-T1S with an onboard physical-termination switch, 10BASE-T1L, SD-card slot, I2C OLED, four rotary encoders, four programmable RGB LEDs, a clear custom-molded case, and a published DB15 pinout. It lists USB-C 5 V input and a 3.7 V / 1000 mA internal battery. The reviewed page does not provide a schematic, BOM, PCB/Gerbers, PHY or transceiver identities, isolation or bus-voltage limits, termination values, dimensions, charge-management details, full connector wiring beyond the DB15 pinout, production quantity, or final recipient scope.
The official page names FreeWili Porpoise Purpose Firmware, the OneWili API for Rust, C/C++, Python, rThon, and WASM, and USB serial terminal access. It does not link a source repository, firmware binary, flashing guide, protocol specification, or software license, so this record does not claim a released firmware archive, reproducible build, update workflow, or reusable software rights.
FREE-WILi says the badge will be available on-site at ICS Village or Vendor Village while supplies last. The official ICS Village schedule establishes the August 6-9 Las Vegas Convention Center setting. At this August 3 pre-event catalogue pass, those are announced availability terms rather than proof of a completed production run, an attendee-wide issue, or an official DEF CON Human credential.
Lifecycle
The official badge page lists RS485/Modbus RTU, CAN/CAN FD, 10BASE-T1S with an onboard physical-termination switch, and 10BASE-T1L as the field-interface set for OT, ICS, and automotive research.
SourceThe official page names FreeWili Porpoise Purpose Firmware, USB serial terminal access, and OneWili API support for Rust, C/C++, Python, rThon, and WASM; it does not link a firmware/source archive or license.
SourceFREE-WILi publishes a dedicated DB15 pinout for the badge, while the reviewed source does not provide full schematic-level connector or transceiver documentation.
SourceOperational history
The catalogue does not claim a released firmware archive, update path, reproducible build, API implementation details, or redistribution rights.
The record can name the published interfaces without suggesting that the badge is reproducible, electrically characterized, isolated, or safe for any specific live system.
The United States pre-event record remains source-backed and image-free rather than copying site imagery, social-media media, screenshots, placeholders, or generated approximations.
The catalogue records announced badge availability, not delivered hardware, a universal attendee allocation, or observed event use.
The record remains attached to the ICS Village event edition without confusing a village hardware project with a general conference-access badge.
