Hello, I was using my Jetson Nano with the DC Barrel jack. The Power is gived by 7.4 Lipo Batery and then I used a 5V step down.
But I connected the wires with inverse polarity and now my Jetson Nano can’t turn on with the barrel jacket.
It works with the Micro-USB and with the headers when I used the same circuit (Step Down and battery).
What can I do?
If you have good hardware knowledge, you can do some checking to find out which components might be damaged by your operation. Otherwise you can try RMA for it.
Where do I have to check in the PCB?
You can check the ESD, load switch and etc. based on the schematic and assembly file of PCB in the design package. https://developer.nvidia.com/jetson-nano-carrier-board-design-files
