I've put together a board design that (hopefully) powers an Omega over Power-over-Ethernet (IEEE 802.3af).
This is the standard that powers many wireless access points and VoIP desk phones using 48 VDC over standard network cables, with up to 15 watts in the initial 802.3af version of the standard.
My board is the smallest thing I could make has electrical isolation from the PoE supply, while supplying 12V@1A, 5V@2A, and 3.3V@2A. Of course, it also connects the Ethernet communications to the Omega, and has an expansion header, as well as 12V and 48V power headers. I specifically designed it for 12V to support powering external hardware, such as 12V LED lighting strips.
The design files are up on Github, and I've just ordered parts for the whole thing. At this point, it's an untested design, so I'll have to wait several weeks to get one in my hands to see if it works.
If anyone is interested in something like this, let me know, and I'll keep you posted about how it goes. There's a non-zero possibility of a group buy if this design works.
