POE with Galileo?

I've been playing with a Galileo at work - and have setup an internal server. I'm connecting to the that internal server IP address via my softphone's ethernet cable - which I believe uses Power Over Ethernet.

I've notice the Galileo board gets quite hot - I only have a basic Temp/Baro sensor plugged in. Seems weird to that it gets so hot. Any high level possibilities on this one?

Regards

There is a temp sensor within

There is a temp sensor within the Quark chip that you can access as well. If you are using the Arduino IDE you can download the examples here https://communities.intel.com/docs/DOC-22272. That will let you compare the internal and external sensors.

What temperature are you seeing?

cat /sys/class/thermal

cat /sys/class/thermal/thermal_zone0/temp

Removing a few zeros and you get the quark temperature (Celsius). The board does run quite warm but is normal.
Upgrading to the latest board firmware can help a bit with the temperature.

Hi Stewart and Tom!

On one device, I'm seeing a temperature of 86C - the other two devices are more like 71C and 68C.

Upon further inspection - I found that I was powering the Hot Galileo with an after market power supply - with an output rating of 9V@650mA. When I compare that to the supplied power supply (5V@2.0A) - I think that might be the difference.

Changing out the aftermarket power supply with the supplied power supply - I'm at 71C. I think that may have solved that little mystery.

Thanks again,

Tom
