Frequently asked questions
Do I need a series resistor for this LED?
Yes. Always use a series resistor to limit current. Calculate it from your supply voltage, the 20 mA rating and the forward voltage, and measure the actual forward voltage on your circuit if you are unsure.
Can I connect it directly to a 3.3 V or 5 V pin?
No. Connecting it directly to a voltage source without a series resistor risks excessive current and damage. Use a resistor sized for your supply voltage.
