Serial Console for the Rock64

[fire219]

Thank you, Mark.
So if I have regular (non-paired) 1-pin cables, I can simply connect the ROCK64 GND to the serial console's GND pin directly, without "fusing" 2 separate wires?
This is my current understanding of how the serial console should be attached using only 1-pin wires:

Tx <---> Rx
Rx <---> Tx
GND <---> GND

Is this acceptable?
Thank again for your help.

That is exactly how it is supposed to work.
