PoE Board Datasheet

The RasPoE shield!

The Ell-i PoE Board is an open source Power-over-Ethernet (PoE) expansion board for Raspberry Pi models B+ and 2B, powering the Raspberry through the Ethernet cable. The basic version contains two Ethernet connectors, one for the incoming connector from a PoE capable Ethernet switch and another one for a jumper cable to connect to the RasPi regular Ethernet connector. We can modify the design to suit your application, contact sales@ell-i.org for details.

The PoE Board is designed to be fitted over the Raspberry itself, with suitable holes for the various connectors on the Raspberry PCB. While the board keeps itself in place when fitted on the Raspberry pin expansion header, we recommend securing the expansion board with screws. There are four screw holes aligned with the RasPi PCB screw holes.

The board contains the circuitry for Power-over-Ethernet physical layer power negotiation, presenting itself as a Class 0 device, and a fully isolated switched mode power supply (SMPS).

The board is IEEE 802.3af compliant.

One thought on “PoE Board Datasheet

  1. […] PoE-piirilevyistä muodoistui oma alaprojekti. ELL-i:llä https://ell-i.org/ oli juuri suunnitteluvaiheessa GPL-lisenssillä PoE-piirilevy Raspberryjä varten, joten päätimme ryhtyä yhteistyöhön. ELL-i suunnitteli, me kommentoimme suunnitelmia; etsimme mahdollisia virheitä, esitimme toiveita ja muutenkin osallistuimme projektiin. ELL-i toimitti meille protolevyjä, ensin itse kolvattavia, loppuvaiheessa valmiiksi kokoonpantuja. Muutaman protokierroksen ja yhden vakavamman bugin korjauksen jälkeen tuotteen designiin oltiin tyytyväisiä. Lisätietoja PoE-levystä: https://ell-i.org/products/poe-for-raspi/datasheet/ […]
