Is it possible to modify the Pi, so that it can receive it's power via Power over Ethernet (PoE)?

I would like to be able to power my unit via the ethernet cable, so that I don't have to worry about running power cords around the place.

but you still need to run network cords? –  Thorbjørn Ravn Andersen Aug 12 '12 at 22:42
@ThorbjørnRavnAndersen that's OK they're well insulated and can handle the outdoors a lot better than a flimsy DC cable. –  darryn.ten Aug 13 '12 at 7:06
HI Recently used one of these. It solves the problem and works well. –  user6983 Apr 17 '13 at 16:32

As previously discussed RPi does not support PoE. And yes you could use a PoE module to hookup power to GPIO. But if you're not up for hardware hacking you could just get a Ethernet/USB power splitter off the shelf.

For up-to-date product list Google is your friend. Searches to use include:

N.B: All except the first will need 2.1mm to USB adapter as well.

I know that we don't usually post links to products, but they are kinda hard to find. And may be worth around keeping until RPi accessories become common place. It's worth noting that the first one even lists RPi compatibility!! :) –  Maria Zverina Jun 26 '12 at 13:44
As the post says, most PoE adapters will require a 2.1mm-to-USB cable or adapter. These can be expensive and/or hard to obtain. As an alternative it's also possible to use a combination of cables (e.g. 2.1mm-to-USB-A plus USB-A to micro-USB) that may be cheaper/easier to come by - more details here. –  psmears Aug 12 '12 at 17:20

Yes, it would be possible. You would need to modify the board with a PoE module:

PoE Module

Which you could hook up to the main power lines, or to the power line on the GPIO, which can be examined in this question.

@Itehnological How is that relevant? As explained, that's at 48V. –  Alex Chamberlain Aug 12 '12 at 19:20

If you want a Raspberry Pi PoE solution that conforms to IEEE 802.3af Standard (PoE), then try the Xtronix Raspberry Pi interface. It is not cheap, but it allows the Pi to be powered via the ethernet cable from a standard PoE hub/switch. The IEEE 802.3af PoE standard defines how devices can be powered over the CAT 5 Ethernet cable.One of the issues the standard addresses is that of safety. A hub/switch that meets the standard allows Poe and non-Poe devices to be mixed safely in the network.

You can buy these via eBay.

thanks for the link! is there any way to get a case for this vehicle ;) ? –  Alex Tape Feb 5 at 9:01

There is an PoE-Modul for the Arduino named "Ag9120-S":

With this, you have to modify the Wiring at the Network-Connector
