Power consumption measurements

10/09/2024, 9:33 AMHello guys! Any idea how to measure the power consumption of each node? (in watts)
Is there any tool to measure it, or could I just plug a voltmeter into the board and read the general power consumption?
Thanks!

10/09/2024, 11:19 AMHello! What I did, is plug the board to a wattmeter, measure while no node was on, turned one node on and calculate the difference

Turing Pi only: 2.8 watts
Turing Pi with one idling RK1: 6.2 W
So one idling RK1 is about: 3.4 W
All the RK1+the board while idling: 17.9 W
Total power consumption under full CPU load: 43 W

10/09/2024, 11:29 AMThank you @Quozul, I was currently working on ML-based algorithms to analyze and improve the power consumed by the board. To do this I would need measurements of the energy consumed for each node, but I think that is not possible. I think the only thing I can do, as you also did, is to connect a wattmeter and measure the overall real-time consumption. Maybe on the jetsons I might be able to trace the power consumption of the GPUs.
