MCU platform
The RP2350 is the successor to the RP2040, bringing Arm or Hazard3 RISC-V cores and enhanced security to the latest generation of hacker badges.
RP2350 handheld-game badge
An official DEF CON 32 electronic badge built around Raspberry Pi RP2350 silicon, a handheld-game-style interface, LEDs, firmware archives, and a DEF CON 32 badge game whose GB Studio project files were published after the event.
Unofficial electronic badge with a documented DEF CON 33 BadgeLife drop schedule
BigTaro's FrogStar 2025 project page calls FrogStar an unofficial DEFCON badge, and the DEF CON 33 Creator Events List schedules a BadgeLife Community Table 1 drop that explicitly names the FrogStar Badge alongside two other BigTaro artifacts. The maker page identifies a Raspberry Pi RP2350, 1.28 inch GC9A01 240 by 240 round LCD, two SAO V1.69bis ports, addressable WS2812B RGB LEDs, an infrared receiver, six buttons, frog-themed CTF and game framing, and a Firmware v1.0 UF2 download with a copy-to-flash instruction. A Tindie listing separately calls it an electronic badge and says it was a Defcon pickup preorder; a later Uberflux listing shows an $80 / seven-sold / 23-remaining snapshot, a DEF CON 34 drop label, and $11 USPS Flat Rate shipping. These sources establish a real independent electronic artifact and a scheduled 2025 event association, not a confirmed completed handout, official DEF CON issuance, admission, exact production count, completed later fulfillment, firmware source release, or reusable-image rights.
Singapore RP2350 and ECP5 FPGA challenge badge
NUS Greyhats' public GreyBadge archive identifies the 2025 GreyCTF badge as GreyMecha/Army, with RP2350-side CircuitPython firmware, KiCad hardware files, an ECP5U_25 FPGA schematic, GC9A01 SPI display, Li-ion power-path circuitry, summit UF2/filesystem releases, and named challenge apps.
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.
SemiTO-V Developer Zone RP2350/GW1N-9 electronic badge project
SemiTO-V's RISC-V FPGA Badge was a limited Developer Zone electronic PCB badge project for RISC-V Summit Europe 2026 in Bologna. Primary team sources name an RP2350 MCU, a GOWIN GW1N-9 FPGA, custom firmware, and a default RV32I core; they say NextPCB produced the boards and planned to bring 25 to the developer workshop. A logistics update then delayed intended June 8 distribution. The source record supports real physical boards and a 2026 event association, not a final unit count, completed recipient delivery, or the precise current post-event design revision.
Planned RP2350 developer-conference PCB badge for Tables Day
Software You Can Love's official 2026 update says attendees of the conference's Sunday Tables Day will receive a SYCL Badge V2. The planned October 3-6 Metro Vancouver event describes the activity as a PCB Badge and identifies selected V2 changes: an RP2350 instead of the earlier ATSAMD51J19 and three AAA batteries instead of LiPo power. A public project repository describes itself as the SYCL conference badge, but the official event material does not map a particular repository commit or design revision to the October handout.
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.
Post-event Pimoroni Blinky 2350 developer-conference badge; organizer allocation unverified
A public post-event app archive by Mainak Sarkar identifies a Pimoroni Blinky 2350 badge as handed out at Workday DevCon 2026 and says it ran the badgeware MicroPython operating system and app launcher. Workday's official pages establish the completed June 1-4 Las Vegas developer conference, but do not directly document badge issuance, recipient allocation, custom hardware, event firmware, or image rights. This is therefore a source-backed event badge record with intentionally limited organizer attribution.
Madrid Hackplayers electronic development-board CTF badge
A source-backed Spanish hacker-conference electronic badge record: the official h-c0n post says Hackplayers finally produced an electronic badge for the sixth 2026 edition, describes it as a fully functional development board, and ties pickup to the February 6 conference registration and CTF start; the public `therealdreg/hcon2026hwctf` repository and Hackplayers post-event write-up document RP2350/RISC-V firmware, tooling, named co-creators, and winner write-ups.
