DC Power Adapter for Nano don't work

Dear ,

When I connect J48 and plugin DC Power Adapter(using on TX2/AGX Xavier), but it can’t power up Nano?
Do I need to do something else inorder to power up Nano using DC Adapter?

The Jetson nano requires a 5V power supply even when using the DC jack.
The TX2/AGX power supply is 19V.
There is protection on the nano to prevent damage when plugging in the incorrect power supply.

Hi dennis_Leetop,

The Jetson Nano Developer Kit is configured to accept power via the Micro-USB connector. You’ll need to power the developer kit with a good quality power supply that can deliver 5V⎓2A at the developer kit’s Micro-USB port. Please refer to the suggestion from below link:


Hi, jetson nano only supports 5V and do NOT plug in a tx2 or agx power supply into nano (19V) dangerous.

Dear Sir,

I make a misstake, change to DC Power Adapter(5V 3A), it works fine, Thanks so much.
