Highlights: 5V/ 2.4A & 1000Mbps - Power micro-USB devices via an Ethernet cable, along with gigabit data transfer (which you can put aside if you only need power) PoE HAT Alternative - Use no GPIO pins. Compatible with Raspberry Pi case with fan or add-on screen. Support Raspberry Pi 3b+ and previous models Extend Powerline - Deliver power to micro USB devices without nearby AC outlets and upgrade them to PoE (Power over Ethernet) from up to 400 feet Replace Power Supply - Remove the need for a separate power supply if the Ethernet cable is a must-have for your micro USB devices Save Your Time - Plug and play compatibility and quick seller response.NOTE: an 802.3 af compliant PoE injector/switch is required to use this device (not included) This gigabit PoE splitter is used to supply power and transfer data to micro USB devices like RPi 3B+ via a single Ethernet cable with the help of an IEEE 802.3 af compliant switch or injector. You don't need a separate power supply anymore. It uses no GPIO pins and is thus compatible with any 3b+ case with a fan or add-on 3b+ screen. It has plug-and-play compatibility with 3B+ and makes it easier for deployment, operation and maintenance in embedded and IoT projects.
