Nametag Blank Large LED

A USB-C powered LED nametag blank: a 160 × 48 mm, 2-layer, 1.6 mm FR4 carrier holding six side-firing OSRAM white LEDs, designed to drop onto an Adom workcell via four large and two medium machine pins.

Part of the RAPID NAME TAGS family. Designed in Fusion 360 Electronics.

Board at a glance


Outline	160 × 48 mm
Stackup	2 layer, 1.6 mm FR4, 35 µm (1 oz) copper both sides
Input	USB-C receptacle (GCT USB4135-GF-A), 5.1 kΩ CC pulldowns
Emitters	6 × OSRAM LW A6SG-V2BA-FK0PN0, 100 Ω series each
Mounting	4 × large machine pins (MP1–MP4) at the corners, 2 × medium
Source	Fusion 360 Electronics (EAGLE)

Circuit

USB-C supplies the board. R1 and R2 (5.1 kΩ) are the CC pulldowns that make the receptacle present as a sink to a Type-C source. The six LEDs sit on a 25.6 mm pitch across the top edge (x = 16, 41.6, 67.2, 92.8, 118.4, 144 mm), each fed through its own 100 Ω series resistor.

The four corner machine pins are the mechanical and electrical interface to the workcell; MP1 at the origin is the front-left anchor the 3D model is keyed to.

⚠️ Incomplete dependency graph. Only the LED resolves to a wiki page today. The two resistor values are keyed by LCSC code rather than a manufacturer part number, and the USB-C receptacle has no page yet. Both need resolving before this board's BOM panel is complete in APM/Nucleus.

3D model provenance

Converted with step2glb molecule mode (OCCT), which anchored the model to the machine-pin markers rather than the STEP's own origin:

molecule_anchored : true
fl_marker         : PIN_LRG:MP1
molecule_up_axis  : z
pin_size          : large   (read from the marker names)
molecule_origin_z : -0.004798
gold_upgraded     : 9

Known gap: no footprint / symbol JSON

This page ships without _footprint.json / _symbol.json, so the board has no wire attach points and will not wire up as a molecule in Hydrogen. Footprint and symbol generation currently fails on EAGLE .brd input with an upstream HTTP 502 — tracked at adom/adom-step2glb#8.

The board itself carries valid MP1–MP4 markers and converts to a correctly anchored model, so it is ready to be re-cut as a molecule once that is fixed.
