## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode terminal of the IR LED; the datasheet gives a reverse breakdown voltage of 5 V (VR), and reverse current must not exceed 10 µA at VR = 5 V. |
| 2 | Anode | passive | Anode terminal of the 940nm IR LED; the datasheet limits are 100 mA maximum continuous forward current and 1000 mA maximum pulse current (pulse width ≤100 µs, duty ≤1%). |
