Hello, I am currently planning to use this device to connect my arduino to the internet.
I was wondering whether it would be possible to use the ethernet cable as a power source ( i.e. PoE ) and be able to run my arduino without any extra wires.
Does anyone know if it’s possible and how it should be done?
That ENC28J60 is not supported by the Arduino libraries. There are libraries for it, but not all libraries work good.
How will you power it ? It needs more current from the 3.3V than some Arduino boards can deliver.
You could use power over Ethernet, and have a dc dc converter to lower the voltage for the Arduino.
