DEF CON 34 Badge

Planned electronic Human badge with SAO specs

DEF CON's official preregistration copy guarantees an onsite DEF CON 34 Human badge, and the official media server publishes DC34 SAO electrical and mechanical specifications that make the 2026 badge a source-backed planned electronic-badge record.

Why It Mattered

It keeps the main DEF CON lineage current before the August 2026 event while marking the evidence boundary clearly: public sources prove a planned Human badge and electronic SAO interface constraints, but not final artwork, firmware, puzzle behavior, shipped production details, or a rights-cleared image.

Hardware

The official DC34 SAO spec sheet documents 3.0 V VDD, a tested 100 mA total supply across both SAOs, two AA batteries, USB-C power-bank behavior that keeps the badge continuously on, GPIO4 as an open-drain CPU wake-up interrupt, other GPIOs with pull-up or pull-down resistors from 2.2 kOhm to about 47 kOhm, I2C devices at 0x3C and 0x19, and mirrored unkeyed female 6-pin SAO headers with published clearance dimensions.

Software & Apps

No public DEF CON 34 badge firmware, game, bootloader, challenge source, or final badge archive is documented in this pass. The record is therefore limited to the official preregistration and SAO specification material until the event or media archive publishes more.

Lore

DEF CON's 2026 homepage places DEF CON 34 at LVCC West Hall on August 6-9, 2026 and frames the theme as Agency. The preregistration notice says guaranteed Human badges must be redeemed onsite and grant one human full access to the DEF CON floor during open hours.

Add-ons & Upgrades

add-on connector pre-event spec

Dual SAO electrical interface

The official DC34 SAO specification documents 3.0 V VDD, 100 mA tested total supply across both SAOs, GPIO pins, I2C devices at 0x3C and 0x19, and mirrored unkeyed 6-pin SAO headers.

Two-AA and USB-C power behavior

The SAO spec states that the badge is powered by two AA batteries and that USB-C power-bank operation keeps the badge continuously on.

Operational history

Issues & Camp Impact

firmware and artifact archive gap note

The public source trail currently documents SAO electrical and mechanical constraints but not badge firmware, bootloader behavior, challenge source, final PCB files, BOM, shipped role variants, or production notes.

Hardware and software fields stay limited to the official SAO spec until DEF CON publishes final badge files or credible post-event technical documentation.

Confidence: source-backed but incomplete
Status: needs post-event archive
Timeframe: pre-event catalogue build
Source note: DC34 SAO spec PDF and DEF CON media-server badge directory path.

missing rights-cleared image note

No DEF CON 34 image is published because no final original badge photo or official reusable raster render with source URL, license, attribution, and processing notes has been recovered.

The entry stays image-free rather than copying ticket graphics, registration art, media-server diagrams, social-media previews, or generated badge art.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: pre-event catalogue build
Source note: badge.gallery image policy and DEF CON 34 source trail.

planned badge caveat note

The DEF CON 34 record is seeded before the event from official preregistration and SAO specification sources.

The catalogue can document the planned Human badge and public electronic interface constraints now, but it must not claim final shipped artwork, firmware, badge-game rules, manufacturing quantities, or all attendee-role variants until post-event sources appear.

Confidence: official pre-event sources
Status: pre-event
Timeframe: before DEF CON 34, August 6-9, 2026
Source note: DEF CON homepage, DEF CON 34 official shop page, and DC34 SAO spec PDF.
