The pinout for the automation header J42 in the “NVIDIA Jetson AGX Orin Developer Kit Carrier Board Specification” document gives functionality by pin #, but it doesn’t say how the pins are numbered for the header (eg whether they number across or down) or where pin 1 is. Is there any information on this? I am looking for something similar to what is given for the 40-pin header J30, where there is a picture of how the pins are numbered, and there is a picture on various sites of the label for pin 1 (eg Jetson AGX Orin Developer Kit User Guide - Hardware | NVIDIA Developer, https://jetsonhacks.com/nvidia-jetson-agx-orin-gpio-header-pinout/).
I saw on the drawing in the Board Specification document that there is an arrow that might indicate pin 1 for each of the headers. However, I was confused because the arrow for J30 on the drawing doesn’t seem to match the pictures, if I am understanding both correctly. Or does the arrow just indicate Row 1?
