Workday DevCon 2026 Blinky 2350 Badge

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.

Workday

Workday's DevCon pages establish the completed event context. This credit does not assign badge design, manufacture, issuance, allocation, software authorship, image rights, or any individual's receipt.

Pimoroni

Pimoroni documents and sells the generic Blinky 2350 platform. This records manufacturer/platform attribution only, not proof of a Workday event-unit production role, customisation, allocation, or media-rights authority.

Why It Mattered

It records a real, hackable developer-conference artifact from a completed 2026 event without converting a public post-event app author's account into proof of an attendee-wide entitlement, an official Workday hardware release, or a fully documented production badge.

Hardware

The app source identifies the event device as a Pimoroni Blinky 2350. Pimoroni's generic product documentation describes that platform as a dual-core RP2350 badge with 872 individually controllable white LEDs, rechargeable LiPo power and USB-C charging, five front buttons, I2C and SWD connectors, four-zone case lighting, and an included case and lanyard. Those are manufacturer baseline facts for the named retail platform, not proof that every event unit had the same configuration, casing, artwork, revision, radio setup, or accessories.

Software & Apps

Mainak Sarkar's post-event Glyph archive says the distributed badge used its built-in badgeware MicroPython operating system and app launcher. Glyph is an independently published, MIT-licensed companion app that reads documented battery, button, and case-light state; it is not asserted to be official Workday software, preinstalled event content, the event firmware image, or evidence of what every participant ran.

Lore

Workday's completed DevCon was a developer conference with a hackathon context at Resorts World in Las Vegas. The public record establishes the event and one attributed post-event app author's device account, but not who designed or distributed the badge, which ticket holders received it, how it was used at the event, or whether its software carried conference-specific interactions.

Badgeware MicroPython app surface

The attributed Glyph README describes the distributed Blinky 2350 as running badgeware MicroPython with an app launcher. This records an independently documented runtime surface, not an official Workday statement about included apps, event firmware, participant configuration, or support.

Compatibility: Pimoroni Blinky 2350 described by the post-event Workday DevCon app archive; exact event-unit firmware parity remains unverified.

Glyph community companion app

Mainak Sarkar's Glyph project is a public companion app for the described Blinky 2350 and references battery, button, and case-light state. It is not represented as official Workday software, preinstalled content, an attendee-wide deployment, or the event's base firmware.

Compatibility: Pimoroni Blinky 2350 / badgeware context described by the app author; no universal event deployment claim.

Issues & Camp Impact

event-unit hardware and firmware parity gap note

The app documentation identifies a Pimoroni Blinky 2350 and badgeware runtime, while Pimoroni documents generic retail-platform features. Reviewed sources do not confirm the exact event-unit revision, board configuration, radio setup, battery, case, lanyard, artwork, serialisation, customisation, firmware image or version, installed apps, firmware license, source release, production run, or hardware-design authorship.

Manufacturer facts are labelled platform baseline only, and no retail configuration is presented as a universal or event-specific Workday build.

missing rights-cleared image note

No Workday DevCon 2026 Blinky 2350 Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

organizer issuance and allocation boundary note

Workday's official event materials establish the completed DevCon dates, venue, and developer-conference context, but do not directly mention a Blinky 2350 badge, badge eligibility, recipient scope, ticket inclusion, quantity, pickup, delivery, fulfilment, designer, manufacturer, or a completed distribution ledger. Mainak Sarkar's public post-event README identifies a device as handed out at the event, which supports this bounded artifact record but not a claim that every attendee or pass holder received one.

The catalogue distinguishes attributed post-event device evidence from official organizer confirmation and does not promote the badge into an attendee-wide entitlement or a Workday-published hardware release.

post-event app and source-license scope boundary note

The repository's MIT license applies to the independently published Glyph app source. It does not prove that Glyph was official or preinstalled, license any event-specific firmware, establish the app's deployment scope, or grant image reuse rights for Workday event media, Pimoroni product media, repository previews, badge imagery, or branding. No factual event-badge image with complete source, license or explicit permission, attribution, and processing provenance was recovered.

The entry remains image-free and keeps app-source licensing separate from badge, event, and media rights.
