AGX Xavier mounting kit for the AGX Xavier production module and carrier boards like the X220 or similar. The screws are inserted from the top of the Xavier module. The 2 (2mm and 2.5mm) spacers are inserted between the Xavier and the carrier board to yield a gap of 4.5mm. The nut is attached below the carrier board. The X220 requires 4.5mm spacing. Other carrier boards may be fine with 4mm spacing.
