One of the challenges of working with an Ethernet connected Arduino device can be having to get both an Ethernet cable and a power cord to the device. Power over Ethernet or PoE solves this problem by running power through the Ethernet cable! To find out more about this useful solution checkout the tutorial we have written to explain the ins and outs of PoE in more detail.
If you are planning on using PoE in one of your own projects you may need the Freetronics 28V Power Regulator for PoE. This versatile device can be used as a general purpose regulator outputting 5V or 7V from an input voltage of up to 28V, however, the regulator is designed to mount onto the EtherTen or EtherMega Arduino compatible boards and pre-regulate the voltage inputted to your device from PoE down to the 7V the Arduino can handle.
