I've just received what I thought was going to be an official ethernet shield, but it's a bit different...
It looks like an official shield (colour, made in italy), but it's clearly a different layout to both the V4.0 shield (this has a microSD slot) and the V5.0 shield (almost everything in a different place - only the sockets, connectors and WIZnet chip seem to have stayed put).
The thing I'm interested in is that the RJ45 has ten pins (plus LED connectors), and that screams PoE to me. Furthermore, pins 9 and 10 have chunky traces on the bottom and pins 7 & 8 have chunky traces on the top out to the row of holes at a (slightly diagonal) 0.1" pitch.
The jack is marked UDE on the top and RB1-125BHQ1A 1035Eda on the back. Some googling with that takes me to http://www.ude-corp.com/frontproduct/product3/lang/en/SmallId/46.html where (unfortunately) that part does not exist, though deductions based on other parts data sheets suggests that 1035Eda is just a date code, and the longer number is a part number, within which HQ1 is the designator for the internal circuit layout. I can't find any jack on the site with an HQ1 circuit.
So, is this a jack with built-in rectifier bridges to extract PoE power? I actually have some PoE injectors kicking around (both cheapo non-standards that just put whatever you inject as + on 4&5 and - on 7&8 and proper standards-compliant 48V ones) so this would be jolly handy. If anyone knows the answer, it might save frying something as I try trial-and-error to work it out!
I can't find any reference on the web other than a page on watterott that has a very slightly different (but closer than any other shield I've found) board that is described in passing as "PoE model" and apparently has a reset problem: http://www.watterott.com/en/blog/Upload-problem-with-Ethernet-Shield
Does anyone know what I've got, or have any other comments? Thanks.
