What is it - A 5v UCTRONICS PoE splitter to split the PoE signal into micro USB power supply and Ethernet in RJ45, so that non-PoE devices can be powered over Ethernet. Reportedly used on micro USB devices like Raspberry Pi, Ethernet Adapter for Fire TV, Cloud Cam, Echo Dot (2nd Gen), Wyze Cam v2, Arlo 2 Pro, ASUS Tinker Board, Nano Pi, Chromecast, and so on What is PoE - PoE enables you to deliver power and data with a single Ethernet cable, and thus fewer wall plugs are needed and fewer cables are messed. It also helps you extend powerline to where there are no AC outlets nearby but your Ethernet cable can reach, up to 300 feet away from the power source Whats special about it - PoE to Micro USB. That means it adds plug-and-play PoE support to Raspberry Pi models even they are not 3 B+ and cannot accommodate a Raspberry Pi PoE HAT. It makes full use of PoE switches because the other end of the PoE port could be any micro USB devices instead of a 48V PoE network device What e
