I have an
Arduino Nano 5v module and I just received an Ethernet Interface Board -
ENC28J60 that runs at
Might sound a dumb question but I will power the Ethernet board from a Voltage regulator that can deliver 3.3v but then I have to connect via
SPI to my Arduino controller. I guess I can't connect my Arduino pins directly to the Ethernet board right? because HIGH in the pin will be 5v instead of 3.3v.
Do I need to add a Voltage divider for those pins connections? And in case I need to what resistance values are the right ones to use?
