I want to use a rj45 connector but confused with different types and pinouts. Here is a one which I can find:
first of all, what this POE thing? Does it provide power to the board and what is its use? If using POE, the RJ45 connector differs like this:
I also found Ethernet shield for arduino which uses pinouts different from the above:
It mentions that it uses a standard RJ45 connector but I could not find one with the documented pinouts.
Can you shed some light on this?
