ICS Village DEF CON 34 Badge

RP2350B multi-protocol OT and automotive research badge with unconfirmed post-date distribution

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. DEF CON's official news confirms the host conference wrapped on August 10, 2026, but the rechecked FREE-WILi and ICS Village pages still read pre-event, so the badge remains a specified offer without a reviewed delivered-run record or official DEF CON admission-credential role.

Why It Mattered

It 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, post-date availability, and credential status.

Hardware

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.

Software & Apps

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.

Lore

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. The September 23 recheck, after DEF CON's official wrap-up announcement, found both pages still presenting those announced availability terms rather than reporting a completed production run, an attendee-wide issue, sold-out status, or an official DEF CON Human credential role.

Lifecycle

Add-ons & Upgrades

field-bus interface officially documented

Multi-protocol physical interface

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.

firmware and API surface officially documented

Porpoise Purpose firmware and OneWili API

The 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.

Issues & Camp Impact

availability and distribution boundary note

FREE-WILi says the badge will be available on-site at ICS Village or Vendor Village while supplies last, and the official ICS Village page announced the August 6-9, 2026 event. DEF CON's official news confirms the host conference wrapped on August 10, 2026, but the rechecked village and FREE-WILi pages still read pre-event and do not establish a completed badge run, recipient count, attendee-wide issue, price, sold-out status, or fulfillment outcome.

The catalogue records announced badge availability, not delivered hardware, a universal attendee allocation, or observed event use.

Confidence: primary official sources
Status: scheduled DEF CON 34 dates elapsed; distribution outcome unconfirmed
Timeframe: rechecked 2026-09-23
Source note: ICS Village DEF CON 34 Badge page, official ICS Village DEF CON 34 page, and DEF CON's official wrap-up news, rechecked 2026-09-23.

firmware source and licensing gap note

The page names Porpoise Purpose Firmware, OneWili, and supported client languages but does not link firmware source, binaries, flashing instructions, protocol documentation, API reference, or a software license.

The catalogue does not claim a released firmware archive, update path, reproducible build, API implementation details, or redistribution rights.

Confidence: official specification page
Status: needs public archive or terms
Timeframe: pre-event source pass
Source note: FREE-WILi ICS Village DEF CON 34 Badge page.

hardware design and safety documentation gap note

The official page gives an unusually detailed feature list but does not provide a schematic, BOM, PCB/Gerbers, transceiver or PHY part identities, isolation details, bus-voltage limits, termination values, charging circuit, battery chemistry, dimensions, complete connector wiring, or electrical safety guidance.

The record can name the published interfaces without suggesting that the badge is reproducible, electrically characterized, isolated, or safe for any specific live system.

Confidence: official specification page
Status: needs engineering archive
Timeframe: pre-event source pass
Source note: FREE-WILi ICS Village DEF CON 34 Badge page.

missing rights-cleared image note

No ICS Village DEF CON 34 badge image is published because the official FREE-WILi and ICS Village pages 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 site imagery, social-media media, screenshots, placeholders, or generated approximations.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and reviewed FREE-WILi and ICS Village sources.

village badge classification note

The source frames this as a hardware badge available at ICS Village or Vendor Village, while the DEF CON 34 event has separate official Human-badge context. The sources do not identify the ICS badge as an official DEF CON admission credential.

The record remains attached to the ICS Village event edition without confusing a village hardware project with a general conference-access badge.

Confidence: official availability and event pages
Status: documented listing; post-date village operation unconfirmed
Timeframe: rechecked 2026-09-23
