These Micro-USB Power over Ethernet (PoE) splitters can simplify your project wiring - and best of all they work to connect any 802.3af-capable router to any Ethernet device, even if it doesn't natively support PoE! The splitter takes a power-injected RJ45 cable, and then separates the data (Ethernet) and power (5 VDC regulated) into two different lines for non-PoE devices.

This is an economical, practical, high-performance, and reliable Isolated 5V 2.4A PoE Splitter with MicroUSB Plug based on IEEE 802.3af standard. It can divide power and data signals from a network cable, and can be used with any PoE injector that is compatible with IEEE 802.3af, and supply power and data for non-PoE network equipment.

Whew, that's quite a few words - but basically: Connect this to your PoE switch or hub, then on the other side of the Ethernet cable, you'll get Ethernet and a high quality 5V power supply, up to 2.4 Amps.

This is perfect for use with a Raspberry Pi 3B+ since it has Ethernet and micro USB power, and 2.4 Amp is plenty of current for even the most accessorized Pi.

Please note that like many active PoE splitters, there's a minimum load requirement of at least 100mA on the 5V power supply. We don't think this is going to be a problem since anything with Ethernet will tend to draw 200mA+, but please keep it in mind!
