80. GPIO Status LED Selection

Aarav is designing a microcontroller board and wants to connect a status LED directly to a 3.3V GPIO pin.

The LED will show simple signals like heartbeat, fault, or system ON.

To avoid overloading the GPIO, he wants the LED to work at low current but still remain clearly visible.

He decides to use a green, 0603 SMD LED.

Help him select a suitable LED from DigiKey.

Make sure it is good for low-current GPIO drive and works reliably in industrial temperatures.
