Radxa Pinout image

#1

Hello, people!
Where can I find a picture with the Radxa zero pinout? I am struggling to understand this official
image, for me to find out which pins are that (which one is TX, RX and 5v/GND).

Because now I see I have to buy a UART to USB connector cable for me to be able to erase the emmc. I was trying to do from the USB port used to power Radxa Zero.

The pinout picture in the wiki still does not describe any I2S (not i2c) interface available on gpio? It this really true? I mean such a powerful chip / board should be able to produce digital sound not only via hdmi.
