I/O ports of an arduino due can only be operated at 3.5 volts. but arduino ethernet shield Operating voltage is 5 volts. can we interface ethernet shield to arduino due board.. . ??? ??
The Ethernet shield is like the other Arduino boards for most part it has both a 5V and 3.3V pin connection. The 5V is regulated to provide and on board 3.3V for circuit operation.
