About this product
A 5 mm round blue LED with a blue diffused lens and a 90 degree viewing angle, emitting at about 460 to 465 nm. It is used as an indicator or backlight in Arduino, ESP and DIY electronics projects. Connect it with a series resistor, since its forward voltage is roughly 3 V to 4 V.

Which series resistor should I use on a 5 V supply?
With about 3.2 V across the LED, a 220 ohm resistor gives roughly 8 mA and a 100 ohm resistor gives roughly 18 mA. Start with 220 ohm and adjust to the brightness you need.
Can I connect it directly to a 3.3 V pin?
It is not recommended. A 3.3 V supply is close to the LED's forward voltage, so it will be dim or may not light, and it still needs a series resistor to avoid excess current.
