This PoE-World device provides an efficient solution for delivering power to a 3B+ or 4 over 328ft of network cable. This device allows power to be carried on 10/100/1000 networks with either 802.3af or passive injectors and switches with a CAT5e, CAT6 or CAT7 Ethernet network cable. Intended for use with or similar PoE switches - this active PoE solution negotiates with the switch to activate power and provide it to the Pi. It is a compact and cost effective power solution. This PoE to 5 volt converter allows you to operate the Pi up to 328ft or 100 meters from a power source. The form factor is perfect for a Pi case - especially the Premium case. The connector pins are available for GPIO and serial use. There is room for a heat sink, and the output power is completely regulated and stable, with much less noise than the hat.
