Jetson Orin NX 16G CSI Pinout

[mgamota2]

I have designed a custom board which has 2 22-pin CSI outputs and I want to interface it with a Jetson Orin NX 16G.

I am a new user so I can only include 1 image, I am happy to provide more. In the image below is the bottom layer of the board (the cable I am using has connections on opposite sides: 22-pin 0.5mm pitch FPC Flex Cable for DSI CSI or HSTX - 10cm : ID 6035 : Adafruit Industries, Unique & fun DIY electronics and kits ) . You will notice that pin 22 has no connection on my board, this is because I do not want to power the rest of my board via the CSI cable. The Jetson Orin NX is powering the rest of this board via USB C, so I assumed it was safe to connect the grounds.

I downloaded the design files for the Jetson Orin Nano (couldn’t find Orin NX) P3768_A04_PCB_assembly_drawing and P3768_A04_OrCAD_schematics(base_version). Based on these two files, I labeled the assembly drawing (assuming the arrow marks pin 1):

Even though the pin numbers on the Jetson Orin NX are reversed from the Raspberry Pi Zero, the left most pin on both boards is 3V3 (pin 1 on Jetson and pin 22 on the Pi).

Am I missing something? These should be equivalent connectors.

My cable burns when I try to power on the Jetson. It works seamlessly with the Pi Zero.

Is my labeled diagram of the Jetson connector wrong? Am I using the wrong design files for the Orin NX? Could my carrier board be a knockoff?

Thank you!

Orin Nano and Orin NX use the same carrier board.

Refer to Jetson Orin Nano Developer Kit Carrier Board Specification https://developer.nvidia.com/downloads/assets/embedded/secure/jetson/orin_nano/docs/jetson_orin_nano_devkit_carrier_board_specification_sp.pdf

for camera connector pinout details.

You seem to be using the correct design files.

Did you test it on our Orin NX carrier board or your own carrier board? Suggest testing on our carrier board first, if available.

Thank you for the prompt response.

Those are the board reference design files that I have been looking at. The board spec document confirms that pin 1 on the Jetson Orin board is 3V3.

This is the only carrier board that I have. I have tried plugging my custom CSI board into both CAM0 and CAM1.

Please check your camera module pinout for compatibility with Jetson Orin Nano/NX pinout. There are multiple versions of camera module pinout depending on the camera module and vendor.

Thank you, the issue was using a different cable (non inverting).
