We have designed our own CM3 board with LAN9514 and the chip operational temperature is significantly higher than that on the RPi. I read the above comments about the power consumption for the Microchip documented operation vs. RPi reduced power approach. I just want to make sure that the excessive heat is normal and the temperature difference between our design and RPi is because of the undocumented modification they made.
The power consumption of this chip is pretty high and I am very disappointed to use it in our solar powered system. Any recommendation?
