Adafruit provides an Ethernet FeatherWing peripheral board for its popular Feather ecosystem of development boards—a valuable option for IoT and automation projects. But it has its limitations. The Feather still needs to be powered separately, and no built-in globally unique MAC address is provided for the user, making deployment hard.

What if we could fix these issues? What if there was a drop-in replacement that would not only provide Ethernet, but also power your Feather, and give you a globally unique MAC? And still be 100% compatible in size, connections and software support? Enter the PoE-FeatherWing!

Features

Simple Ethernet + Power for Your Feather Projects!

Arduino and CircuitPython example code is available on GitHub. This code includes examples like Arduino "Web Client Repeating", which allows you to make repeated HTTP requests using DNS, as well as others.

Early Bird Rev 2 Board

Testing of the initial 100 units showed a few small things that could use improvement. Most users would never notice a difference in normal use, so we are offering 100 early bird boards at a discount price, and they will ship shortly after the campaign ends.

Here is an explanation of the small differences in the early bird boards:

Rev 2 UnitsRev 3 Units
Minimum voltage under load4 V4.3 V
TransformerLink-PP with higher EMIHanrun with lower EMI
Max output power*3 W4 W

*A USB-powered Feather only supports 2.5 W, so both 3 W and 4 W are just fine.

"Well, I for one am very impressed. It always amazes me when someone like Patrick looks at something like an Ethernet FeatherWing and says to themselves, “Hmm, not bad, but I can do better.”"
