Title: Arduino M0 Pro driving 5V W2812B RGB LED strip
Post by: NorseGod on Nov 12, 2017, 06:51 pm
Do I need a level converter from 3.3V to 5V or has anyone got it working without one when feeding the strip @5V and with a 470ohm resistor in series (as recommended)?

Cheers

1) yes
And
2) yes, but it might not work for all strips under all conditions and temperatures.
