## Bundled KiCad library
This page also ships the complete, self-contained KiCad library for the board: **29 symbols**, **16 footprints**, **15 3D models** (STEP + GLB), all linked.

- `USB3toEthernetDataOnly.kicad_sym` — all 29 schematic symbols
- `USB3toEthernetDataOnly.pretty/` — 16 footprints
- `USB3toEthernetDataOnly.3dshapes/` — 15 STEP + GLB models

### Install
1. Download this page's files and extract, e.g. `~/Documents/KiCAD/USB3toEthernetDataOnly/`.
2. KiCad → **Preferences → Configure Paths**, add `USB3TOETH_3D` = `<extract-dir>/USB3toEthernetDataOnly.3dshapes` (so footprint 3D models resolve).
3. Add to your **sym-lib-table** / **fp-lib-table**:
   ```
   (lib (name "USB3toEthernetDataOnly")(type "KiCad")(uri "<extract-dir>/USB3toEthernetDataOnly.kicad_sym")(options "")(descr "USB3-to-Ethernet Molecule symbols"))
   (lib (name "USB3toEthernetDataOnly")(type "KiCad")(uri "<extract-dir>/USB3toEthernetDataOnly.pretty")(options "")(descr "USB3-to-Ethernet Molecule footprints"))
   ```
