Depends on your definition of beginner. It's trivial to put a nrf52 module (like [1]) in a PCB design and wire a USB socket to it; just make sure to route the data lines as a differential pair in kicad (add protection diodes if feeling fancy). And speak a little prayer that it actually works as intended. No need to understand what any of that means.

Of course the notion of using such a module might be a step up from beginner for you, but IMHO it's more about the understanding. But I agree that there is no definite definition.

Disclaimer: I'm a beginner by my definition.
