Power over Ethernet

To keep the FeatherWing small, simple and inexpensive, we do not include PoE support. However, it's a common request that some people want to simplify cabling when the device is far away.

This all-in-one solution will let you plug an Ethernet cable to a PoE switch/hub then split into data and a Feather-friendly micro USB connector on the other

And plug that directly into the Feather. For long power runs there might be a slight voltage droop but since the regulator on board will reduce the input voltage to 3.3V for the chip and peripherals (all Feathers are 3.3V logic) it should not be noticable
