BOM finished

A project log for PoEPi: Pi Zero Power over Ethernet with PHY

It can power the Raspberry Pi Zero over Ethernet. The board also adds an Ethernet Phy to the Raspberry Pi Zero to give you full Ethernet

The component selection and BOM are finished! Its always the hardest part and can require a lot of attention to detail. While creating the BOM i realized that I had sized one of the Caps wrong on the PoE circuit. With this cap to small the power would have been spotty at high loads.

The BOM is formated for mouser. If you are using Digikey or some other supplier you can use Mousers BOM tool to export the manufacturer part numbers then load them to your distributor. The cost to make one board is .... $55! Seems expensive, well its mostly in the transformers. The cost drops to about $32 at 100. Several of these parts can be switch for low cost versions. I used high quality caps to avoid blowing things up early in the building.

Im still looking for feedback if you can give it. I want the PoE circuit to be solid before I start adapting other designs. I will be ordering the board next week hopefully.
