I downloaded the compressed package called Jetson Xavier NX Developer Kit Carrier Board Design Package (P3509 A01) from the official website.

I need to use a lower version of the PCB circuit diagram (.brd) file of Jetson Xavier NX. Could you help me convert the PCB circuit diagram (.brd) file to version 16.6?
P3509_A01_Allegro_layout.rar (6.1 MB)

That is the file we can support. Hope someone can help on this.
