I have read in several threads that using external power with the Ethernet shield normally can produce overheating problems... and I need to tackle that
I have tried a 9V/444mA AC/DC transformer, using Vin and Gnd pins for connections, and I get the shield to work, but the Duemilenova power regulator gets really hot.
Even so, I am not sure if this is within the operational range of the devices involved here... My piece of hardware project is quite critical and I need the set to work 24/7. I am not sure if in the long range I can damage the boards or if it will stop working properly.. after all, many electronic devices get like that
In case you guys think that I should change the AC/DC transformers, should I decrese the voltage or the current? Will I be safe with a 7.5V input?
Thanks a lot guys!
