    Hello, forgive my English, it's a translation.

    I have replaced LED WS2812 with an APA102, now nothing works and it is connected in the same way as the previous installation.
    I wonder if I need something else to connect leds apa102 to the raspberry, some manual about it?

    Thank you

    Did you actually adjust your config file to the new LED type?

    Yes, I have configured apa102 in the configuration.

    I have read that a 3.3v / 5v logical converter is needed but now I only have the one that I attached in photo ......... would it be valid?

    Hello, please, can you tell me if that converter could work in my configuration?

    How would I have to connect it?

    can you please tell me something, and what can I do

    should work yes, the input pins are going to rpi and the output pins to the leds
