1,Effective Solution: This POE-World device provides an effective solution that can power for 3B+ or 4 through a 328-foot network cable. 2,Suitable Cable: This device allows the use of 802.3af or passive injectors and switches using CAT5e, CAT6 or CAT7 Ethernet network cables to supply power on 10/100/1000 networks. 3,Connector Pins: This POE to 5V converter allows you to operate the for Pi at a distance of 328 ft or 100 meters from the power supply. The size is very suitable for Pi shells-especially for Premium shells. The connector pins can be used for GPIO and serial use. 4,Large Radiator: There is room for a large radiator, and the output power is fully adjustable and stable, which is much less noise than the for hat. 5,Designed Function: Designed for or similar POE switches. This active POE solution negotiates with the switch to activate power and provide it to the Pi. This is a compact and cost-effective power solution.
