## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (-) terminal of the LED, marked by the cathode mark on the package; reverse voltage VR max 5 V. |
| 2 | A | passive | Anode (+) terminal of the LED; forward current IF max 25 mA (60 mA peak at 1/10 duty, 1 kHz), VF 1.7 to 2.3 V at IF=20 mA, requires a series resistor. |

## CAD (KiCad official)

- Symbol: `17-21`
- Footprint: `LED_SMD:LED_0805_2012Metric`
- 3D model: 0805 (KiCad packages3D, STEP)
- 3D model files: `17-21-etched.step` / `17-21-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `17-21.step` / `17-21.glb` are the bare package body.
