At this August 3, 2026 source pass, the listing shows 5 sold and 95 remaining, with four pickup labels: DC34 Reddit Meetup Wednesday, DC34 Reddit Meetup Thursday, and DEF CON 34 BadgeLife 1 and 2. The maker describes an ESP32-S3, custom four-layer PCB, 128×128 OLED, SX1276 LoRa, GPS, magnetometer/IMU, five Cherry MX-compatible switches, a rotary encoder, 61 WS2812B LEDs, a buzzer, 3D-printed parts, a Li-ion battery, USB-C updating/charging, a LoRa mesh, Wi-Fi geolocation fallback, and a PWA. The public MIT-licensed firmware repository documents v1/v2/v3 platform variants, a 915 MHz SX127x-class LoRa mesh, GPS/status PingMessage data, PlatformIO build paths, RPC, and remote USB/BLE/web configuration; v4.0.0 publishes v3 and v2 binaries. A separate Fusion360/STL CAD repository and web-companion repository are public but have no detected license. This is a source-backed pre-event independent BadgeLife record, not proof of final fulfillment, a final production BOM, radio/regulatory performance, safety certification, universal update compatibility, official DEF CON admission status, or reusable-image rights.
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.
Maker-documented RP2040 community eBadge with firmware, art, and SAO sources
RestiaAshdoll8's public DEFCON-SG-2026-Div0-Tingkat-eBadge repository says it contains source code and relevant files used in a physical Div0 Tingkak eBadge. It preserves a UF2, RP2040/Pico-focused source, artwork, and SAO project files. Its sources conflict on event identity: the repository title names DEF CON Singapore while its firmware menu banner says SINCON 2026 BADGE. This record keeps the DEF CON Singapore association maker-declared rather than resolving that conflict into official event status.
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.

As of this pre-event source pass, it is not a delivered-run or official DEF CON admission credential.
Pre-event RP2350 infrared game badge with conditional LoRa score sync
Laser* Tag Badge DS is an independent BadgeLife project planned for DEF CON 34. Its maker page describes an RP2350-based infrared tag game with a 915 MHz LoRa score-sync option and QR fallback, while a public late-July update says the boards have arrived and final assembly and flashing are in progress. The record is pre-event and independent; it is not an official DEF CON admission badge.
Pre-event RP2350B interactive Simple Add-On planned for DEF CON 34
ParallelLogic's Uberflux listing, public MalO_SAO source/design repository, and first-hand Hackaday.io project diary document a planned DEF CON 34 Simple Add-On based on the SCP-1471-A MalO setting. The marketplace's August 4, 2026 snapshot lists $50, 43 sold, and 57 remaining. The repository says the units are intended for online sale and DEF CON 34 handout in August 2026, identifies an RP2350B, 16 MB external flash, 1.5-inch 128 by 128 grayscale OLED, standard six-pin SAO header, USB-C, capacitive touch, potentiometer, buzzer, microphone, hall sensor, IMU, ambient-light sensor, IR transmit/receive, NFC/RFID, and LED banks. Its project diary confirms the work is ongoing and documents early prototype testing. The repository declares the work CC BY-SA 3.0. This is a source-backed pre-event independent badge record, not proof that a final revision has shipped, that all promoted functions are complete, that every radio/sensor interaction is safe or private, that a named third-party lore asset grants image rights, that the project is DEF CON-issued, or that it grants admission.
Montreal CH32V203 and RP2040 badge by Electronic Cats with LoRa and NFC
A Canadian REcon 2026 official electronic badge by Electronic Cats, documented by the official sponsors page and the public badge-recon-2026 repository as a CH32V203 primary board with an RP2040 daughterboard, an SSD1306 OLED, a Semtech SX1262 915 MHz LoRa radio, an NFC PN7150 daughterboard, four buttons, USB-C, and a rich LoRa radar, chat, flag, NFC flag-hunt, magspoof, and Simon challenge surface.

The project owner describes a proximity-controlled badge with a BLE number-station puzzle, red-versus-blue proximity game, autonomous social/dance mode, expressive BLE MIDI instrument, tamper-evident mode, Setup menu, and optional hardware CTF. In follow-up comments, the maker reports about 55 units made so far, signed firmware with a distinct key pair per badge, a constrained giveaway/sale plan, and RGB blank boards that omit the OLED, LiPo, and ESP32 module. No public repository, schematic, firmware release, final availability ledger, or reusable-image permission was recovered.
French ESP32-C6 B.A.D.G.E. with OLED, SAO, and BLE color propagation
The official THcon 2026 B.A.D.G.E. page documents an ESP32-C6 electronic badge with the Badge3000 WiFi access point, an I2C OLED at address 0x3C, and BLE padlock and one-time-password challenges for the May 5-6 tenth edition in Toulouse. A May 13 first-hand attendee teardown identifies the distributed board as an ESP32-C6-WROOM-1 build with an SSD1306 OLED, WS2812 RGB LED, ATC24C04 EEPROM, SAO connector, single-cell battery/TP4056 charging path, and USB-C CH340C serial bridge; it also documents the delivered firmware's BLE color-command propagation behavior.

An official Temporal Replay 2026 developer-conference badge documented by the MIT-licensed temporal-community/badge.temporal.io repository as an ESP32-S3 app platform with an OLED and LED matrix, a Doom port, MicroPython, and infrared boop badge-to-badge networking, for the May 5-7, 2026 event in San Francisco.
CH573F BLE virtual-pet and CTF electronic badge
A source-backed Peruvian Unknown Security Conference 2026 electronic-badge record that joins the official pass's lanyard-and-badge inclusion with Electronic Cats' self-described official Pwn Llama badge repository. Its public history shows hardware work before the June 4-6 Lima event and a July documentation update.
Pre-event RP2350 CTF-adventure BadgeLife badge for DEF CON 34
BigTaro's own Wordweaving Badge project page and live Uberflux listing describe an independent DEF CON 34 top-down adventure / CTF badge. The current maker payload shows a $120 100-unit presale with 41 sold, DC34 pickup, and post-con shipping; it also says the badge would be $140 at the maker-described Hacker Warehouse booth during the conference. The maker describes an RP2350 with 4 MB flash, 16 RGB addressable LEDs, a 128×128 grayscale display, rechargeable LiPo via USB-C, and a fully addressable SAO port. It publishes game, CTF, multiplayer, word-building, and optional-component claims, but says hardware documentation and a stub firmware will only be provided after the conference. The project page says 30-plus CTF puzzles while the live listing says 35-plus, so the record preserves a broad maker-described challenge surface rather than resolving the discrepancy. This is a source-backed pre-event independent badge, not proof of final hardware/firmware, shipment or pickup, game availability, CTF completion, venue authorization, DEF CON affiliation, conference admission, or reusable-image rights.
