Questions about the use of USB components

I want to use Arduino as a controller.

At this time, should Arduino and bbb be connected via USB?

Since it is a non-WiFi model, I am worried about using USB WiFi.

thank you

Use the BBB alone without Arduino or use 3.3v logic. Stay cautious with 5v logic as it will damage the processor(s) via the pin headers on the BBB or ruin your peripherals you choose to use.

P.S. No, the Arduino should not be connected via the BBB USB.
