Anyone who enjoys building electronic projects using the awesome Raspberry Pi single board mini PC. Might be interested to know that this week Silvertel the UK-based manufacturer has released a circuit and PCB layout for a new 5V PoE adapter board.
The 5V PoE adapter board enables you to power your Raspberry Pi over Ethernet and the documents provide you with a list of all the components you will require to purchase to construct your PoE splitter board.
The Silvertel PoE adapter board has also been used to power the MarS i.MX6, Olimex A10-OLinuXino-LIME, BeagleBone Black, Element 14 RIoTboard and its components cost less than £7 or $11. The Electronics Weekly website explains :
“As the adapter board can be used to power any 5V device, up to a power of 9W, it is suitable for powering a Raspberry Pi via a standard USB cable or DC connection.
The module provides an IEEE 802.3 compliant PoE input, capable of taking PoE power and data from any PoE injector. The 5V/1.8A output is provided on a USB connector or DC plug. The board provides an IEEE802.3af signature to avoid any potential damage that could be caused by incorrect or shorted Ethernet cables. 5V-PoE-adaptor-board-back.”
