Best way to monitor power consumption on Ultra96-V2

Support

My goal is to monitor the power consumption of my Ultra96-V2 Board. First I tried to use the PMBus Overlay from PYNQ, but I only got the voltage out of the sensors. I guess either there is no current sensor or the current sensor is not supported (I think rather the latter :joy:).
When you want to reproduce what I mean on an Ultra96-V2 Board.

from pynq import pmbus, DataRecorder
rail = pmbus.get_rails()
print(rail)

I’ve already read into this similar pynq community post. But it would be soo convenient to just use the PMBus Overlay and Python to monitor the power consumption.

Did you find a method to read the current or power out of the Ultra96-V2? Or did you use other methods?

Thank you for your help! :relaxed:

The functionality is present in the master version of the Ultra96 GitHub repo but it isn’t in a pre-made image yet. There are some limitations - in particular total board power isn’t available only power on main 5V bus post-regulation. This results in the standby rail not being monitored.

I don’t know when the next Ultra96 release will be. You can try building your own image using the instructions in the repo and elsewhere in the forum.
