System current Monitor for NVIDIA Jetson C Xavier Developer Kit

Hey, is there a way to monitor the Current drawn by the Xavier Board. The built in power Monitor only show voltage output and a fixed Calculated Current Power Monitor App note

hello Ashja,

could you please check again, the linkage to “Power Monitor App note” was broken.
please also refer to Software-Based Power Consumption Modeling;
you may get rail current in milliamperes via INA3221 power monitor.
thanks

hey @JerryChang ,
The link has a session or expire token you can search by this name “Jetson TX1 and TX2 Voltage and Current Monitor Configuration”

This Module is integrated in the Xavier?

hello Ashja,

yes, Jetson AGX Xavier series modules integrate a three-channel INA3221 power monitor;
you may check the information by using sysfs nodes.

hey @JerryChang ,
thanks for the reply . isnt the INA3221 module used here only for Voltage monitoring ?.Also can you elaborate on this?

hello Ashja,

please check developer guide, Software-Based Power Consumption Modeling;
you will get rail current in milliamperes via in_currentN_input, thanks

hey @JerryChang ,
thanks for the help.
