    That's an interesting finding... but...
    The board is now broken? What was burned, exactly? XR806 module or just the USB to UART converter or LDO?
    Helpful post? Buy me a coffee.

    So how long did you manage to use it?

    Maybe you have a short between 5V+ and D+ or D- on USB C?

    Or maybe there is a stray solder ball on the PCB...

    removed module. VCC to module is 5V, but that should have been OK it seems
