With a new 25-watt power budget and enhanced management capabilities, the recently ratified IEEE 802.3at Power Over Ethernet Plus (PoE+) standard finally allows embedded systems developers to create “no new wires” devices including large HD video displays, cameras, speakers, mass storage and other peripherals with a single Cat5/5e/6 cable as the only external connection. The new 802.3at standard takes PoE technology from niche applications like Wi-Fi access points and IP phones into the mainstream of the embedded market. And PoE+ brings many long overdue improvements in cost, reliability, energy efficiency, manageability and installation simplicity that have previously been unattainable in most embedded systems.

Please read more below about how PoE+ can give your embedded products significant competitive advantages in the marketplace.

ADI Engineering’s 802.3at PoE+ Products

Cinnamon Bay SBC with 802.3at PoE+

Based on the Intel Atom Z5xxP series, Cinnamon Bay SBC is a tiny, low cost embedded SBC with optional 802.3at. With features including power consumption as low as 3.5W, on-board hardware offloaded HD video decoder, optional -40 to +85C extended temperature SKUs, and a rich set of peripherals and expansion capabilities, Cinnamon Bay SBC serves as the ideal platform to build advanced PoE+ powered embedded systems.

802.3at PoE+ Option Module

ADI’s PoE+ Option Module adds 802.3at PD functionality to any Ethernet design – only an off-board RJ45 and PoE capable Ethernet transformer are required.

PoE Technical Articles

COTS Journal Article: Power over Ethernet Blends Distributed Power and Data Management

Steve Yates, ADI Engineering’s Founder and CTO, writes about how 802.3at is starting to make inroads into military and commercial embedded applications.

Embedded Intel Solutions Article: 802.3at PoE and Intel Atom Processors Advance Embedded Devices

Another article by ADI’s CTO Steve Yates discusses the growth of PoE+ in embedded applications, and how low-power CPU technologies like Intel Atom work in concert with the new PoE+ standard to enable complex embedded sytems targeted at the mainstream of embedded applications.

ControlDesign.com tackles the issue of PoE interoperability and the advantages and the disadvantages of extending these standards to provide additional functionality.

Case Studies

Microsemi/Purdue University Case Study

This case study examines how PoE was used by Purdue University to achieve installation cost savings of $350-$1000 per unit for their campus-wide Wi-Fi network.

Inova Solutions LED Wallboard PoE Case Study

Inova Solutions is a global provider of real-time visual communication solutions that serve applications including mass notification and public messaging. When Inova needed to upgrade its line of LED wallboard displays with PoE technology and the latest generation Intel embedded processors, ADI Engineering provided the underlying platform based on a COTS SBC customized with PoE support. Two end products are now seeing widespread use in call centers, transit applications, and university campus-wide crisis communication systems.
