If you use the UART-To-Serial-Converter provided with the board, you can just connect the Black jumper to B, the White to W and the Green to G. The UART uses 3.3V levels. 

Quite a long line. Could you break it?

Much trailing whitespace. Block copy? :^)

Sascha accepts fixup commits, so you can create a fixup locally
and

  git send-email -1 --in-reply-to="<20220711141246.3331160-2-j.zink at pengutronix.de>"

to have it appear correctly threaded.

Cheers,
Ahmad
