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 built-in, 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

• PoE: Isolated IEEE 802.3at Class 1, Mode A and Mode B Power over Ethernet, with 4 W of output power available
• Globally unique MAC address: A Microchip 24AA02E48 provides a built-in globally unique MAC address, allowing actual field deployment without having to change and recompile code for each device.
• Works with existing software: A WIZnet W5500 Ethernet controller ensures full compatibility with existing software written for the Adafruit Ethernet FeatherWing.
• Arduino driver: Works with the standard Arduino Ethernet driver
• CircuitPython driver: Works with the standard CircuitPython WIZNET5K driver
• Drop-in replacement: With board size and connections identical to the Adafruit Ethernet FeatherWing, it's a true drop-in replacement
• Giant Board compatibility: A solder jumper allows for easy compatibility with the Giant Board Feather form-factor Linux SBC, without needing to add a fly wire for the IRQ (Interrupt Request Signal).

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.

Combine with M4-Shim for really compact PoE builds!

Instead of using it with a standard Feather, you now have the option to combine this FeatherWing with our M4-Shim to create really compact PoE systems.

NOTE: Pin headers are included but not installed, so you have the freedom to choose stackable headers if you need to!
