Has Anyone Measured the Power Consumption of the BeagleY-AI Board?

General Discussion

I’m reaching out to the community to see if anyone else has measured the power consumption of the BeagleY-AI board, as I’m experiencing some concerning values. I’ve noticed that the board runs quite hot—so much so that I can barely touch it for long periods without discomfort.
My Measurements

Here are the readings I’ve collected:

With Ethernet and CPU in idle: 1.23A at 4.76V => 5.85W
Without Ethernet and CPU in idle: 1.03A at 4.76V => 4.90W
With Ethernet and 4 CPU cores under stress: 1.33A at 4.76V => 6.33W

These values seem quite high, and I’m worried about potential overheating and power efficiency issues. If anyone has similar experiences or can share their measurements, it would be incredibly helpful. How do your values compare?

which kernel version? (uname -r) we hacked in cpufreq in later builds..

$ uname -r

Kernel 6.12.33

cat /etc/os-release
ID=arago
NAME=“Arago”
VERSION=“2025.01”
VERSION_ID=2025.01
PRETTY_NAME=“Arago 2025.01”
CPE_NAME=“cpe:/o:openembedded:arago:2025.01”

Thank you for your reply.

So probably mainline as is… it would be running at full speed..

Do you have any value in idle mode ?

Just idling in xfce.. v6.1.83 production kernel (Debian 12)…

Edit, that current is measured on 120V AC:

Thank you.

A standard AC-DC converter loses around 20%, so it looks like we’re dealing with the same power consumption.

Is the design of the BBAI not power-efficient, or is the AM67A using all the power? If anyone has the answers, I would be happy to learn more about it.
