Just an FYI. Xavier NX and TX2 NX are pin compatible. Here is a post that says the Xavier NX will not work with the Nano dev board A02. The post goes on to say that the Nano dev board B01 is compatible with the Xavier NX, which “Should” make the TX2 NX compatible with the Nano dev board B01.
Maybe someone from Nvidia can just confirm this for us. @WayneWWW
