@@ -0,0 +1,86 @@+# 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.

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.++## Bill of materials++| Ref | Qty | Part | Notes |+|---|---|---|---|+| LED1–LED6 | 6 | OSRAM **LW A6SG-V2BA-FK0PN0** | [`adonis/lw-a6sg-v2ba-fk0pn0`](https://wiki.adom.inc/adonis/lw-a6sg-v2ba-fk0pn0) |+| R3–R7, R9 | 6 | 100 Ω 0603 100 mW 75 V | LCSC `C22775` — MPN unresolved ⚠️ |+| R1, R2 | 2 | 5.1 kΩ 0603 100 mW 75 V | LCSC `C23186` — MPN unresolved ⚠️ |+| J2 | 1 | GCT **USB4135-GF-A** USB-C receptacle | no wiki page yet ⚠️ |+| MP1–MP4 | 4 | Adom machine pin, large | mechanical |+| U$9, U$10 | 2 | Adom machine pin, medium | mechanical |++⚠️ **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.
