The PoE shield will be compatible software-wise with the official Arduino Ethernet Shield, but also supply power to the board via Power over Ethernet.

Project Status

Design, BOM, schematic, and PCB layout complete, PCBs received from Laen and parts on order with Digikey.

Notes

Notes from Rev. 1

  • For LM5070 library part put a notation for where pin 1 goes.
  • C6 footprint does not match BoM (C6 should be 0603 or footprint to 0805)
  • D2 has no silkscreen
  • Fix footprint on U2 (Pads are too far apart lengthwise)
  • Fix footprint for U3 (it's just generally wrong)

Ideas for Rev. 2 =

  • Could switch the main transformer to a POE13W3VERS-R (1.8/3.3/7V) or 7491192912 (3.3/5/12V) to avoid the need for secondary regulation all-together
