**DETAILS**

Power over Ethernet for Arduino

The solution is called “Power-over-Ethernet” (commonly referred to as “PoE”), which puts a DC voltage onto specific pairs of the Ethernet cable so that devices connected to the network can use it as a power source.

And it shows the simple way to use PoE system for Arduino with low-tech (and cheapest) way to inject power into an Ethernet segment is to modify an Ethernet cable.

A neater way to achieve the same end result without doing any cable cutting or soldering is to use a device called a “*PoE splitter*” that connects between the LAN cable and the device. It has a socket into which you can insert the LAN cable, and then connects to the RJ45 port on the Ethernet shield and the DC jack on the Arduino.
