Read a device id by my application, and also can be seem directly from the board

I’m trying to read an unique id for identify a jetson board (used for like a device registration), also this id should be seen by human eye directly.
I noticed there’re 2 ids printed on board:


could you help to confirm:

  1. are these 2 id guranteed to be unique for each jetson board?
    include all jetson families devices(NX and Xavier…).
  2. which one (of the two) is recommended to use, and by which command can read them.

The S/N is for module id.

so this id is the one I can use for my scenario, correct? I searched around, does this command read the id?

cat /proc/device-tree/serial-number

Yes, that command should match the S/N
