As the title mentions, the barrel port temporarily lit up with smoke hence after.
Up until now, I’ve been using a 5v/4A(centre positive) adapter with no problems. However, after installing a new 9260 wifi card onto my Jetson nano, this incident began to occur when i plugged in the barrel port
Right now, i removed the jumper pin and am testing my board with the micro usb adapter and thankfully my board looks fine, but i would like to know why this has happened, and if there are any tests to check if my jetson nano is ok.
If smoke has been released, there should be signs of a burned or damaged component. Take a good look at all the components and take a picture for us to see. With these details you can not know that it may have failed.
Upon further inspection, it looks like component D32 has been damaged (first image on imgur). Do you have any possible idea for the cause? Or how this damaged component can hamper my Jetson Nano?
From the symptoms, it sounds like you did something wrong.
Either the card you installed is bad, or you accidentally shorted something.
Try feeding power from USB or from the GPIO header. If it works, you’re lucky. If not, buy a new board.
Hi Michael, I forwarded this thread to our HW engineers, thanks for including the picture - the component that burnt out is for the power select header. So that could explain why only Micro-USB power delivery works now. Just browsing the thread, we don’t think it’s related to Key-E wireless module, unless like Snarky said it was inserted backwards (if that’s even possible) or was electrically faulty. Perhaps another component got shorted or there was an issue with the power supply that occurred.
Regardless, the board is still under warranty so you can RMA it for a replacement if you want. In that case we could also take a closer look at what happened.
