LayerOne 2025 GLiTCh BadgE

RP2040 and iCE40 glitching badge for hardware hacking

LayerOne 2025's GLiTCh BadgE was a conference electronic badge and hardware-hacking platform centered on an RP2040, iCE40 FPGA, voltage glitching, crowbar control, SWD, AVRISP, analog monitoring, multiple USB modes, and CLI-driven experiments.

Why It Mattered

It adds LayerOne to the North American badge record with a badge that is not only an attendee artifact but also a fault-injection, debug-probe, and hardware-hacking lab used alongside the event's Hardware Hacking Village challenges.

Hardware

The public repository documents an RP2040 dual-core ARM Cortex-M0+ controller, ICE40 FPGA, voltage glitcher, crowbar circuit, SWD interface, AVRISP wiring, analog monitoring, basic 12-bit logic-analyzer behavior, USB-C, exposed headers, solder-jumper configuration points, and VR1/VR2 potentiometers for target-voltage control.

Software & Apps

The README and docs describe UF2 flashing through the RPI-RP2 boot volume, CLI control through Python/PySerial, normal USB mode with multiple CDC interfaces and mass storage, DAP mode as a CMSIS-DAP probe for pyOCD/OpenOCD/Keil workflows, DFU mode for firmware updates, and command families for glitching, crowbar triggering, SWD, AVRISP, ADC streaming, GPIO, RGB, and USB-mode switching.

Lore

LayerOne's Hardware Hacking Village page says the 2025 electronic badge was the GLiTCh BadgE and points attendees to the repository, while the village challenge list tied it into Open Sauce badge, ESP32 BluTag, RP2040 timing, and custom shadetree companion-hardware exercises.

Add-ons & Upgrades

debug-probe firmware documented

CMSIS-DAP and SWD debug mode

DAP mode presents the badge as a CMSIS-DAP probe for pyOCD, OpenOCD, Keil, and SWD target debugging while keeping a CLI serial interface available.

measurement workflow documented

ADC streaming and 12-bit logic analyser

The README describes ADC streaming over a serial interface and frames the badge as a basic 12-bit logic analyser for low-rate signal inspection.

programming interface documented

AVRISP programming mode

The hardware-hacking guide documents AVRISP wiring and commands for initialization, target identification, flash reads/programming, and fuse access.

Issues & Camp Impact

AI-generated documentation caveat note

The repository README explicitly warns that later documentation may include AI-generated docs, so this pass treats the repository as useful project evidence while preferring official LayerOne pages for event claims and recording documentation limits.

Hardware and firmware features are kept to repeatedly corroborated repository and guide statements instead of overstating uncertain generated prose.

Confidence: repository README
Status: documented with caution
Timeframe: current LayerOne 2025 pass
Source note: LayerOne 2025 GLiTCh BadgE README.

hardware errata caveat note

The README records hardware caveats including an error on one charlieplexed LED and a reversed 3-pin JST SWD connector, plus solder-jumper and target-voltage configuration notes.

The record presents the badge as a real hardware lab platform with documented errata rather than a polished reference design without caveats.

Confidence: repository README
Status: documented
Timeframe: badge repository notes
Source note: LayerOne 2025 GLiTCh BadgE README.

missing rights-cleared image note

No LayerOne 2025 badge image is published because the available official-site, repository, and GitHub-attachment visuals have not been paired with complete original-photo provenance, license, attribution, and processing notes; a May 22, 2026 repository recheck found the only tracked PNG is a script/test screenshot rather than a badge hero image.

The entry remains source-backed and image-free rather than reusing generated, teaser, attachment, screenshot, or undocumented badge imagery.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
