Linux ADS-B badge with Winglet OS 2.0
Aerospace Village's DEF CON 33 badge record documents the DC32 ADS-B badge hardware returning for DC33 with new software, Winglet OS 2.0 release artifacts, DC33 SAO support, and an ADS-B accessory ecosystem.

The official DC33 badge page says Rare Circuits collaborated with Aerospace Village on the 2025 SAO for the Aerospace Village ADS-B Badge.
SourceOfficial publisher of the DEF CON 33 badge page and repository owner for the AV Badge 2024 software and documentation archive.
SourceIt is a unusually capable village badge: a Linux single-board computer that natively receives 1090 MHz ADS-B, maps nearby aircraft with GPS context, exposes data over network interfaces, and keeps its OS, firmware, tutorials, and release images public.
The public trail documents the same DC32 badge hardware returning for DC33: an ADS-B receiver with onboard PCB antenna and optional external antenna, GPS, built-in Wi-Fi, dual-core processor, 128 MB DDR3 RAM, 8 GB eMMC, microSD slot, replaceable 18650 battery, USB-C PD charging, USB-C dual-role behavior, blinky lights, and an SAO connector supporting I2C, UART, CAN Bus, and more.
The repository documents Winglet OS as a Buildroot-based embedded Linux image using custom winglet-kernel, winglet-boot, and winglet-gui submodules. The DC33 v2.0 release added increased ADS-B range/reliability, Map Scope and GPS View, flight-board improvements, custom SD media, Wi-Fi scanning/connecting, light mode, USB host reliability fixes, optional 3 A charge rate, and Aerospace Village DC33 SAO support.
The badge bridges aviation security, software-defined radio culture, and DEF CON badgelife without being the mainline DEF CON badge. Aerospace Village explicitly framed it as a DC32 badge returning for DC33, so this record treats the DC33 artifact as a software/support/accessory refresh of the same badge hardware rather than inventing a new board revision.
Lifecycle
The badge natively receives and displays nearby aircraft using 1090 MHz ADS-B signals, with an onboard PCB antenna and optional external antenna path.
SourceThe badge includes an SAO connector that supports I2C, UART, CAN Bus, and more; the DC33 release explicitly adds Aerospace Village DC33 SAO support.
SourceThe FAQ documents USB-C Ethernet access and SSH to root@192.168.100.1, with Wi-Fi and USB-C platform caveats called out separately.
SourceWinglet OS 2.0 added ADS-B range and reliability work, Map Scope, GPS View, flight-board improvements, SD-card custom media, Wi-Fi scanning, USB-host reliability fixes, optional 3 A charging, and DC33 SAO support.
SourceThe badge provides GPS own-ship position on a moving map, and the FAQ documents manual coordinate fallback when GPS lock is unavailable.
SourceOperational history
The record preserves the RF and navigation limits without implying universal aircraft tracking or software-selectable ADS-B bands.
The record presents Winglet OS as publicly buildable and hackable while making clear that toolchain, USB, and access workflows are not frictionless for every host.
The catalogue records the optional antenna path while preserving the modification risk and RF-protection context.
The catalogue treats this as a DC33 software/support/accessory refresh of the Aerospace Village ADS-B badge, not as a newly designed 2025 board revision.
The record remains source-backed and image-free rather than copying official page graphics, store imagery, repository screenshots, or generated imagery without complete provenance.
