Does the WS2812B 2020 RGB LED SMD have a built-in decoupling capacitor, or is it necessary to add a 100nF capacitor for each LED?

Soldered Support:

This product does not have a built-in decoupling capacitor. Best practice is to add 100nF for each LED as you mentioned.

Original message (Croatian)

hvala na upitu, taj proizvod nema decoupling capacitor. Najbolja praksa je dodati 100nF za svaku ledicu kao što si naveo.
