How to use a uart in pynq-z2's ardunio

This url
shows that we could use uart in pynq-z2’s ardunio,But we find it is confusing for me with the pins’name.
It shows UART peripheral use pins D0,D1,but there is no D0,D1 in the ardunio pins’name on our pynq-z2 board.

I’m confused how to contact lines with uart on ardunio in pynq-z2.
could anyone help me :slight_smile:

D0 and D1 are standard notations for arduino pins.

So on pynq-z2 picture you show, they are on the up right corner (upper row).

thanks,your info is very important.
