## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (negative, marked '-') terminal of the green LED; the datasheet gives max continuous forward current IF 20 mA (80 mA peak, pulse width ≤0.1 ms, duty ≤1/10) and VF 2.5-3.1 V at IF=20mA. |
| 2 | A | passive | Anode (positive, marked '+') terminal of the green LED; the datasheet gives max reverse voltage VR 5 V and reverse current IR ≤5 µA at VR=5V. |
