Hackaday Europe 2025 SAO Badge
Berlin reuse of the Supercon 8 SAO badge with revamped firmware
Hackaday Europe 2025 reused the Supercon 8 Simple Add-On badge concept in Berlin: an SAO-focused badge with I2C/GPIO exposure, MicroPython lineage, revamped Europe firmware, Supercon contest-winner add-ons, and badge-hacking ceremony context.

Hackaday published the event, badge, schedule, and add-on evidence for the 2025 Europe record.
SourceWhy It Mattered
It closes the public Berlin Hackaday Europe run through 2025 while keeping the reuse lineage explicit: the event badge is real and source-backed, but its hardware identity descends from the 2024 Hackaday Supercon 8 SAO badge rather than a newly independent European board.
Hardware
Hackaday's Europe preview describes the badge as a showpiece of SAOs, with exposed I2C buses and GPIOs inherited from the Supercon 8 badge context. The upstream Supercon 8 sources document a Raspberry Pi Pico W main badge, six SAO connectors, individually addressable GPIO, split I2C buses, and included touch-wheel, LED-spiral, blank protoboard, and CH32V003 proto-petal add-ons.
Software & Apps
Hackaday says the Supercon unit ran MicroPython and that the Europe badge would have revamped firmware. Public sources also state that the badge could flash CH32V003-style add-ons through the SAO port, while the upstream repository preserves the MicroPython setup and I2C interaction workflow.
Lore
Hackaday framed the 2025 Europe bag as an expanded SAO ecosystem: four Supercon Add-On Contest winners, the Supercon touch wheel, LED spiral, and CH32V003 prototyping boards, with Sunday lightning talks before the badge-hack showcase and a Saturday-night badge-hacking ceremony on the official schedule.

Issues & Camp Impact
firmware archive boundary
note
The public Hackaday sources announce revamped Europe firmware but this pass did not recover a versioned final Hackaday Europe 2025 firmware release distinct from the upstream Supercon 8 repository trail.
Software claims stay limited to the announced revamped firmware, MicroPython lineage, SAO-port flashing statement, and upstream public repository workflow.
- Confidence
- current public source trail
- Status
- needs deeper archive recovery
- Timeframe
- current catalogue build
- Source note
- Hackaday Europe 2025 ticket preview and Hack-a-Day/2024-Supercon-8-Add-On-Badge repository.
missing rights-cleared image
note
No original documentary photo or official upstream raster render of the Hackaday Europe 2025 badge has been recovered with a reusable license, permission basis, attribution, and processing trail.
The badge stays image-free rather than copying Hackaday article media, repository photos, screenshots, social media, or generated approximations.
- Confidence
- local project policy
- Status
- needs licensed original replacement
- Timeframe
- current catalogue build
- Source note
- badge.gallery image policy and May 21, 2026 repository/API review.
repository license caveat
note
The upstream `Hack-a-Day/2024-Supercon-8-Add-On-Badge` GitHub API metadata reported `license: null` during this pass.
Repository photos and renders are retained as evidence only unless a separate explicit image license or permission basis is recovered.

reuse lineage caveat
note
The public evidence identifies the Europe badge through the Supercon 8 SAO badge lineage with Europe-specific firmware and add-on distribution, not as an independently new Berlin PCB.
The record should remain tied to Hackaday Europe 2025 while preserving the upstream 2024 Supercon hardware/software lineage.
