Customer:

Can the WS2812 RGB LED Strip (PAMETNA RGB LED TRAKA WS2812 30LED/M 5V IP20) be connected directly to a Micro:Bit? We are interested in purchasing 10 units of these strips for educational use.

Soldered Support:

The WS2812 RGB LED Strip operates at 5V, while the Micro:Bit board can output a maximum of 3.3V. Direct connection is not possible because the voltage is too low to ensure proper operation of the LED strip.

Original message (Croatian)

hvala Vam na upitu. Sama pametna RGB LED traka radi na 5V, dok Micro:Bit pločica može dati maksimalno 3.3V. Direktno spajanje u tom slučaju nije moguće jer se zbog premalog napona ne bi mogao osigurat pravilan rad LED trake.
