Hi @teamswiftgik, sounds like an awesome project - while I wish we could fullfil your request, unfortunately at this time we are unable to provide Orin NX modules (sorry about that), however encourage you to look into the EDU discount for Orin Nano:

Also SeeedStudio makes an Orin NX kit, and Holybro makes an OrinNX Pixhawk autopilot - perhaps they would be able to help.
In the meantime, did you try using torch2trt on your PyTorch CNN or exporting it to ONNX and see if trtexec can run it with higher performance?
