My bad. It is not in the document but it was printed at the bottom of the PCB.

  1. GND
  2. RTS
  3. NC
  4. RXD
  5. TXD
  6. CTS

the pinout from sittisaks is correct.
Please note that CTS and RTS are not connected.

Is the RXD and TXD Pin of the J44 header connected to the UART1_RXD and UART1_TXD, or to the UART2_RXD and UART2_TXD?
Thanks in advance.

It’s UART1, you can check the schematic in DLC. [url]https://developer.nvidia.com/embedded/dlc/Jetson-Nano-Carrier-Board-Reference-Design-Files[/url]
