ESP32 over USB with my Raspberry Pi? (without using wifi)

    I'm using SK6812 RGBW LEDs and was told I needed to use an ESP32 to control the LEDs instead of directly connecting it to the Raspberry Pi.


    I've installed WLED on an ESP32 and it works great over wifi but can I just connect the ESP32 to the Raspberry Pi (Hyperion) and have them communicate using USB?


    Should I use something different on the ESP32 besides WLED?

    ESP with WLED over USB:

    Code
        - Gerätetyp: Adalight/Momo
    - Geräteausgabe: /dev/ttyUSB0
    - Geräterate: 115200

    Geräterate/Baudrate is limited to 115200

    Thanks so much! Does the limited baudrate (115200) cause any problems or latency?


    Is it better to use WLED over WiFi or another method maybe?


    EDIT: What about solutions like HyperSerialESP32 or HyperSerialWLED?


    EDIT2: Do I need an ESP32 for my SK6812 RGBW? I'm using an RPi 4 but I heard you can't connect them directly?
