What is the best way to control my SK6812 via USB?

  • Hi,


    I am looking forward adding hyperion to my setup with a Raspberry Pi 4. I know most people control leds using the GPIO ports of the pi4. But that's not what I'm looking for. I plan on replacing the pi by a Debian server pc in a few weeks, and this doesn't have GPIO ports so USB is the only way. So I thought it should be better to go USB right away. I have 2 questions :


    - What is the best USB device for controlling my SK6812 light strips?

    - could it add significant delay?


    Thanks in advance for your help, have a great day

    USB is usually limited to baud rates.

    Delay is not significant, Wifi 5ms LAN/USB < 0.5ms

  • Thanks for your answer.

    I would prefer to avoid using an external device to control my hyperion. Then I guess using GPIO is the only way. But that will require a different solution when I will move to my PC. Is there modules that can be plugged in a PCIe slot that gives pins with sufficient baud rates for SK6812 leds ?
