Two Step Models of Jetson Orin on the Download Center

[alexa1]

It appears that there appear to be two 3D step files of the Jetson Orin floating around. I am attaching an image of the two step files side by side.

I obtained step file (i) from "Jetson Orin NX Series and Jetson Orin Nano Module 3D CAD STEP model”.

I obtained step file (ii) from "Jetson Orin Nano Developer Kit 3D CAD STEP model”

Additionally, comparing the CAD to the data sheet, it appears that model (i) on the left shows the maximum GPU height, rather than the median.

Can you please help with the following?

1. Confirm which is the correct model of the card. It would appear that (i) matches the drawing in the design guide, and that (ii) is incorrect and does not accurately represent the envelope of the Orin, despite being the CAD model used in the developer kit file.

2. Is my assessment that the card shows the height of the GPU centroid to be at its maximum correct?

3. Clarify whether we should expect the GPU Centroid height to be 2.476 +/- 0.15mm or is it 2.626 - 0.3mm.

Hi, please refer to module STEP file for that and module data sheet for dimension. The GPU centroid height is 2.326 ~ 2.626mm as you can get in module data sheet.
