Power over ethernet? There’s a shield for that.

Like making ethernet-enabled Arduino sensors, but hate running wires to power them? Well, rather than building a complicated energy-harvesting system or relying on batteries, you might want to take a look at powering them using the same Ethernet cables that are used to transmit data to them. This can be a bit messy to implement, but luckily the folks at Freetronics have cooked up this Ethernet Shield With PoE to do the dirty work for you. Just plug it in, hook up a single power supply at your router, and you are good to go! [via sparkle labs]

  1. The Freetronics Ethernet shield is really that good. Plenty of prototyping space on the board, just like their TwentyTen. I use them in my series of open-source Arduino tutorials at tronixstuff.com/tutorials.

  2. If anyone is using this shield I have POE injector cables I am giving away for the cost of shipping in the classifieds section of the forums.
