## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode (negative terminal) of the red LED; return path to ground/negative supply in forward bias operation; reverse voltage rating 5V maximum. |
| 2 | A | passive | Anode (positive terminal) of the red LED; forward bias operation requires connection through a current-limiting resistor to positive supply with forward voltage 1.8-2.4V @ 10mA. |
