DC power jack

Dear all,

I have a Jetson Orin AGX Dev Kit. So far, I’ve only powered it using the original NVidia power supply, which connects to Orin via a USB-C cable. However, I am going to install Orin in a mobile robot, so I need to power Orin with a battery through the DC power jack, not the USB-C cable. The problem is that the Orin’s jack connector is short-circuited, and I suspect the issue is with the diode. I recorded a video to show you the problem. The YouTube video is available [here](https://youtu.be/WkGAFSQrVfQ). Please watch it for a better understanding.

I would like to speak to someone from NVidia about this. Could you please tell me how I can contact NVidia regarding this? Is my hypothesis correct? If not, what could the problem be, please?

Thank you in advance.


Yes, seems it is shorted to GND. You can run RMA for it, or try removing the suspected diode.

Hi @Trumany, thank you so much for your reply.

Since there’s this issue with the DC power jack, can I use the USB-C interface to power my Jetson Orin? Is there any risk in using my Jetson the way it is (DC power jack damaged), but powering it through the USB-C interface, please?

That’s ok since it worked well with USB-C supply before. The damaged diode is isolated by MOSFET, should be no problem. If you have concern still, you can remove it.

Alright, thank you so much for clarifying this matter.
Have a nice day.

Hi @Trumany

I have another question regarding this matter, so I’ll just post it here and I appreciate if you can help me.
I have a 12V battery to power my ground robot, and this battery is used to power my Jetson Orin AGX. I’m using the USB-C cable to connect the Orin to the battery, but my Orin doesn’t turn on (not even the LED turns on). Should I use 19V instead to power my Orin? The power supply that comes with the Orin (which also has a USB-C cable to connect to the Orin) outputs different configurations of V, A and W. Hence, we are not sure whether we should change our battery or just the jumpers in our Orin here.

Thank you so much once again.

Not sure if it is related to your 12V battery, but you can try other 19V ones.
