## CAD (KiCad official)

- Symbol: `LTE-C9901`
- Footprint: `LED_SMD:LED_0603_1608Metric`
- 3D model: 0603 (KiCad packages3D, STEP)
- 3D model files: `lte-c9901-etched.step` / `lte-c9901-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lte-c9901.step` / `lte-c9901.glb` are the bare package body.
