Adafruit Power over Ethernet (PoE) Module is designed for Raspberry Pi 3 Model B+ with four header wires. This module uses just one Ethernet cable for both power and data. The PoE module can attach to the four input wires on the Raspberry Pi 3 Model B+ board and provide regulated 5V/1.5A output. This module requires female-to-female jumper wires to get the Ethernet wires to the module and two wires to bring the 5V back to the header. The PoE module is RoHS2 compliant and is available in 56.4mm x 20.3mm x 13.2mm dimensions.
