From Silvertel: "PoE Power for Raspberry Pi 3 model B+"
The new Raspberry Pi 3 model B+ design has made it even easier to add PoE hat, without the need for extra cables. The GPIO connector will provide all the connection required for PoE. Silvertel, a UK manufacturer of POE, telecom and power modules, have released a circuit and PCB layout for a 5V PoE adapter board ideal for the new Raspberry Pi 3 model B+ design. This PoE hat design uses the Raspberry Pi 3 B board’s GPIO connector to access the Ethernet transformer and power lines to provide a simple neat PoE solution. The information provided is available for free download and use by any manufacturer of accessories or general hobbyists. The information pack provided includes: a full bill of materials (parts readily available from on-line electronic component suppliers), a circuit schematic and the PCB layout. The Ag9905M is the smallest 12W PoE solution available at this time but Silvertel is constantly surprising the market.
