Issue dossier
AoSC's eChallengeCoin page says Micro-USB and one large touch pad, while the CircuitPython Coin M0 profile that AoSC links as the eChallengeCoin-specific build says native USB-C and three capacitive touch pads. Both sources mention three NeoPixel groups and a speaker. This pass did not recover a revision note, schematic, product BOM, photo with cleared technical annotation, or maker clarification resolving whether the pages describe the same final 2026 unit, a transitional revision, or differing interface vocabulary.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.

AoSC maker project page
Primary maker page for the 2026 planned 40-brass-coin statement, terminal text adventure, the page's Micro-USB/one-touch-pad/three-NeoPixel-group/speaker/no-battery/46-gram claims, Choose Your Own Charity context, U.S. mail or DEF CON pickup wording, and the linked CircuitPython build. Its product and promotional media do not state reusable-image rights.

AoSC organizer form and fulfillment page
Primary organizer form explaining that a $100-or-greater youth-STEM-charity donation may receive a 2026 coin, with U.S. mail or in-person DEF CON pickup options. It contains an upload flow for donation proof but does not publish a privacy, data-retention, tax, charity-verification, delivery, or final-allocation policy.

independent current-event index
DEF CON.outel.org's independently maintained planning index lists 2026 eChallenge Coin / eChallengeCoin entries among current DEF CON 34 items. It corroborates public current-event discovery only; it is not official DEF CON issuance, a complete technical source, fulfillment proof, or image-rights grant.

official CircuitPython board profile
Official CircuitPython profile linked by AoSC as the eChallengeCoin-specific build. It identifies ATSAMD21G1A/4 MB flash, three RGB-NeoPixel groups, three capacitive touch pads, one speaker, CircuitPython/Arduino support, and native USB-C—details that conflict with the maker page's Micro-USB and one-touch-pad wording rather than settle it.

Primary organizer source for the $100-or-greater youth STEM charity donation statement, may-receive wording, pickup/mail selection, U.S.-address restriction for mail, and donation-receipt upload requirement. It does not establish tax deductibility, legal charity status, organizer verification practice, personal-data retention/security, promised allocation, or completed fulfillment.

AoSC / Bradán Lane STUDIO · retrieved 2026-05-15
Primary source for the planned 40-brass-coin run, no-sale/gift framing, Sara and the Missing Artifacts terminal-game claim, one large touch pad, three NeoPixel groups, speaker, no battery, 46-gram brass, Micro-USB serial-device wording, CircuitPython/macropad statements, planned donation threshold, U.S. mail/DEF CON pickup, and student-brass statements. It does not prove final component parity, completed production, donation verification, delivery, official status, game-source license, or image reuse permission.

CircuitPython · retrieved 2026-05-15
Primary official board-profile source for the ATSAMD21G1A, 4 MB flash, native USB-C, three RGB-NeoPixel groups, three capacitive touch pads, speaker, CircuitPython/Arduino, and USB serial/MIDI/HID/disk surface. It is linked by AoSC as the eChallengeCoin build but does not reconcile its USB-C/three-touch claims with the maker eChallengeCoin page's Micro-USB/one-touch wording or prove 2026 production parity.
