Radxa Pinout image

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.


You can check it out here https://wiki.radxa.com/Zero/hardware/gpio

Thank you so much!!

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.
