Power supply via PoE ?

Hi @all,

is it planned or currently possible to power the board directly via PoE ?

Thanks
Mario

No, there's no support for PoE.

Careful use of this cable set may be an option:

It seems not to be compatible with the Gbit Ethernet. :(

Currently I use for my RASPi this Splitter but I think I can take it also for the C1 (incl. Gigabit network)

Basically I search for a board where I can put the PoE cable direct in - without splitter etc.

cheers

Rasperry pi b+ consume upt to 3W-600mA https://fr.wikipedia.org/wiki/Raspberry ... rry_Pi_3) then it's compatible with POE

Odroid hc1 at least 4W up to 14W for 5V. I result in intensity up to 2,8 A. which is not alowded by the POE standard https://en.wikipedia.org/wiki/Power_over_Ethernet

Warning ethernet cable should not support this intensity. :oops:

rosbeef, you are mistaken, 4w is nothing for poe. The amps limiting is for the ethernet cable, not for the device 5v power, that's why the poe voltage is normally at least 24v to minimize the amps in the network cable.
odroid can with no problem be powered by poe and a splitter cable.
