Qustions about the power supply and application of Jetson AGX Xavier

Hello,

I have some questions about the Jetson AGX Xavier system. I see there is 65W power supply with AC cord included in the box, but I want to use the system outdoors, where the electrical outlet may be unavailable. I am wondering how to power the system outdoors.

We plan to use the system to accelerate the computation of isotope identification using neural networks built using TensorFlow. I am wondering if it is possible to connect the system to a laptop or a cell phone and use them to control the system, like transferring the files stored in a laptop or a cell phone to the system (the files contain detector measurements), using the system to process the data, and transferring the results back to the laptop or the cell phone (for viewing the results). If you have any suggestions to our application, please let us know.

Thank you very much!

It can run on 12V suppply. but to run at full clock speed, best would be to get a 12 to 19.5V DC-DC converter. get at least 5A

one of these would work great: https://www.amazon.com/uxcell-Converter-Regulator-Waterproof-Transformer/dp/B01H97ETP8

Thank you very much! For the 12V supply, do you mean batteries?

And I am wondering how to connect the output of the DC-DC converter to the developer kit.

As far as I know the dev kit it uses a 5.5mm OD and 2.5mm ID plug.

Koosdupreez, you say it is better to hit 12-19volts, however the manual says otherwise. https://static5.arrow.com/pdfs/2018/12/12/12/22/1/565659/nvda_/manual/jetson_agx_xavier_thermal_design_guide_v1.0.pdf
“5.1 POWER SUPPLY
The choice of voltage for the input power supply to the Jetson AGX Xavier has an
impact on the overall power efficiency. There are two input voltage rails for Jetson AGX
Xavier: SYS_VIN_HV and SYS_VIN_MV. The input voltage for SYS_VIN_HV can range from
9V to 19V while SYS_VIN_MV requires 5V. For optimal efficiency, a lower voltage power
supply should be used. For example, a standard 9V power supply provides better
efficiency over a 19V one. As the input voltage increases from 9V up to 19V the module
operating efficiency will drop off.”

This is saying 9v is the closet to native power rails. Or do you know something else?
