PoE+ Splitter Design
« on: December 04, 2019, 08:17:39 pm »
I'm working on a Raspberry Pi 4 project where I may need the higher wattage of PoE+ rather than straight PoE.  The design of the enclosure doesn't make it possible to expose the Raspberry Pi's ethernet jack and I have concerns about a non-PoE+ jack supplying PoE+ currents.

Conceptually, a splitter seems pretty straight forward.  Use a PoE+ RJ-45 jack with magnetics, a Silvertel or similar PoE buck module with required bridge rectifiers connected to the centertaps, and connect the RJ-45 outputs across to a standard RJ-45 jack (pin 1 to pin 1 and so on).

Am I overlooking something?

Thanks,

Jon
