Jetson Nano 2 GB Carrier Board U9 Component burned


My Jetson Nano 2 GB Developer Kit which has 945-13541-0000-000 serial number, is burned out. I was trying to use Jetson nano from GPIO Pin, and i gave 5V volt from my ASUS 350 Watt power supply. In Developer Kit’s carrier board, i am seeing only U9 Component burned out.

Could you please tell me what is the U9 compenent?
Where can i find U9 component?
May i replace it with new U9 component?

Also, if it not possible to replace the component via soldering, May i buy new carrier board (without Jetson Nano Module)?


U9 is a buffer 74LVC1G126GW. You can try changing it if burnt. Carrier board is not for sale separately.

We have provided the 74LVC1G126GW buffer. We soldered carefully. However, the pins 1 and 5 I have shown in the attachment seem to be short circuited to each other.

Is this normal?

If possible, could you check and let me know?

Yes, pin 1 and 5 should be shorted together.

Thank you very much.
