Sold-out pre-event Lepi Labs UPDI-programmer moth Simple Add-On for DEF CON 34
Lepi Labs' own Uberflux listing identifies UPDeeDeeI as a DEF CON 34-drop moth Simple Add-On. Its August 4, 2026 marketplace state is out of stock, with seven sold, zero remaining, and a $35 listed price. The maker says a CH340E USB-to-serial converter supports UPDI programming of compatible ATtiny devices, names an onboard ATtiny814 with two RGB LED eyes, and describes USB-C plus a flexible FPC tongue used as a functional USB cable. It also claims configurable 3.3 V or 5 V UPDI voltage, SAO or included CR2032 power, and v1.1 pre-event corrections including an FPC power fuse. Lepi Labs' first-hand DC34 announcement corroborates planned Friday and Saturday BadgeLife Village drops. This is a source-backed pre-event independent programming-tool SAO, not proof of final board revision, safe programming configuration, USB/FPC durability, compatible target coverage, delivery, host compatibility, DEF CON organizer affiliation, conference admission, or reusable-image rights.
People
The Lepi Labs product page says UPDeeDeeI is based on Stefan Wagner's UPDI programmer. This preserves a narrow source-attributed basis credit without asserting code reuse, license, technical authorship of this SAO, or image-reuse authority.
SourceThe live Uberflux listing identifies Lepi Labs as the maker, and the first-hand announcement speaks as the group. This records its public maker/publisher role without inferring individual engineering authorship, production responsibility, DEF CON organizational status, or image-reuse authority.
SourceThe Lepi Labs product page says Art by makanioverlord. This records the stated artwork credit only; it is not an image-reuse license or proof of hardware, firmware, manufacturing, or event role.
SourceUPDeeDeeI is a current badge-side programming tool rather than a generic blinkie: its maker exposes the bridge chip, target family, voltage selection, companion controller, and a specific pre-event correction trail. The catalogue can preserve that utility without turning it into a universal flashing guide or electrical guarantee. The final record makes the right distinction between a maker-described functional FPC cable and tested, safe compatibility with every host, target, cable orientation, or user workflow.
The source describes a CH340E USB-to-serial converter, USB-C connector, flexible FPC tongue with functional USB pads, onboard ATtiny814 MCU, two RGB LED eyes with hot-glue diffusers, configurable 3.3 V or 5 V UPDI voltage, and power through the SAO connector or an included CR2032 battery. It says v1.1 adds CH340E bypass capacitors, corrects power-select and UPDI-select routing, routes GPIO to the SAO connector, corrects the CR2032 holder footprint, and adds a fuse to the FPC power connection. It does not publish electrical schematics, a final BOM, USB-C or FPC current limits, fuse rating, power sequencing, exact voltage-selection mechanism, target pinout/cable instructions, target-device compatibility list, physical-durability test data, certification, final v1.1 verification, or a general safety guarantee.
The maker says the SAO can program UPDI devices such as ATtiny microcontrollers and cites Stefan Wagner's UPDI programmer as its basis. It does not provide firmware or source for the onboard ATtiny814, host utility versions, CH340 driver requirements, operating-system support, programming protocol settings, wiring diagrams, fuses/lock-bit handling, recovery guidance, target firmware examples, toolchain, license, or a supported-target matrix. The source therefore supports a narrow maker-described UPDI capability, not a ready-to-run programming procedure.
Lepi Labs describes the moth as a wearable embedded-development aid that can also act as a decorative SAO when not used for programming. The group announced scheduled Friday 12:30 PM and Saturday 2:30 PM DEF CON 34 BadgeLife Village drops. Its listing says v1.1 boards were ordered and, if identified prototype issues remain unresolved or later problems arise before DEF CON, buyers could receive a refund or shipment after the event. These are independent pre-event offer terms, not proof of stock, completed drops, final production, fulfillment, DEF CON authorization, organizer status, or access rights.
Lifecycle
The listing names an onboard ATtiny814 connected to two RGB LED eyes, with power from the SAO connector or an included CR2032 battery. It does not publish default firmware, LED electrical data, power budget, battery runtime, voltage limits, connector pinout, host matrix, or final behavior.
SourceThe maker says the FPC tongue contains functional USB pads and can act as a USB cable when folded for tension, alongside a USB-C connector. It says the tongue is durable but may crumple with repeated use. The source does not publish cable-current limits, orientation details, USB signal testing, cycle testing, mechanical precautions, device compatibility, or warranty/support terms.
SourceThe listing says a CH340E USB-to-serial converter can program UPDI devices such as ATtiny microcontrollers and names configurable 3.3 V or 5 V UPDI voltage. It does not publish wiring, driver requirements, target support, protocol configuration, level validation, fuse/lock-bit handling, recovery procedure, or a safe universal programming guarantee.
SourceThe live Lepi Labs product page shows a $35 price, seven sold, zero remaining, and a DEF CON 34 drop label. The team separately announces scheduled BadgeLife Village drops. These current source statements do not establish final run size, paid-order status, physical stock, exact drop allocation, handoff, delivery, refund, or post-event outcome.
SourceThe maker says v1.1 boards were ordered and lists CH340E decoupling, power-select, UPDI-select, GPIO, CR2032-holder, and FPC-fuse corrections from v0.1. It says unresolved prototype issues or later pre-event problems could lead to a full refund or shipment after DEF CON. These are maker-described plans, not proof of final validation, shipped v1.1 units, correction outcome, refund, or delivery.
SourceOperational history
The catalogue credits the public source basis without supplying unverified programming steps, device-specific firmware claims, a reproducible build, or reuse terms.
The record does not turn product-level programming and cable claims into a universal target-support list, safe-voltage recommendation, USB certification, durable-cable guarantee, or complete electrical design.
The catalogue classifies the moth as an independent pre-event BadgeLife artifact associated with DEF CON 34, not an official credential, organizer-issued badge, or access item.
The record remains source-backed and image-free rather than copying the maker listing image, prototype/renders, Reddit media, screenshots, social posts, placeholders, or generated approximations.
The catalogue retains current offer and remedy language without claiming completed distribution or a finalized production run.
