Hi, in Xavier AGX, I would like to create additional UART ports on the unused expansion header pins (please see attached) to obtain four UART ports in total.

How should I proceed?

Thanks

hello arvindsr,

Jetson Xavier NX brings three UARTs out to the main connector;
please also refer to NX Product Design Guide for the pin description.
thanks
