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 and parts received, revision 1 board assembly is in progress.
Notes
Notes from Rev. 1
- Package has silkscreen already, just none on bottom of rev. 1 boards: For LM5070 library part put a notation for where pin 1 goes.
- Fixed in revision 2:
C6 footprint does not match BoM (C6 should be 0603 or footprint to 1210) - 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
