Ethernet Tap Board - Components

After ordering the boards I went off to research the various components and source them in. Step one was to use the BOM from Github to see what all is still currently available, it's 2-3 years old now. After researching and contacting DigiKey I have come up with this as my orderable BOM:

1,CL10F474ZB8NNNC,C1
5,CC0603KRX7R9BB104,C2 C6 C7 C8 C9   
1,UVR1A682MHD,C3
2,CL10B105KP8NNNC,C4 C5
1,690-005-299-043,CON1
1,CDBA140-G,D1
1,XZCBD53W-6,D2
1,MZ1608-102Y,L1
16,009176002032006,IDC-CONN
1,RC0603JR-0722RL,R1
2,RC0603JR-0710KL,R2 R3
1,RC0603FR-07100RL,R4
2,RC0603JR-074K7L,R5 R6
8,G6KU-2F-RF DC5,U1-U8
1,AP2120N-3.0TRG1,U9
1,PIC16F1454-I/SL,U10
2,MC74HC595ADG,U11 U12
1,MMA8653FCR1,U13

I then fed that into the BOM tool at Octopart who went around and found where they're available and what they cost. I chose to just order all the parts from DigiKey to make it easy but, in theory, you could save $80 if you order from all over the place. I'm guessing shipping would more than consume that. Here is the Octopart BOM to use, feed that to whatever supplier you'd like.

The relays, G6KU-2F-RF, are the most expensive part at $22 each so the total BOM today is $197 (plus shipping). Somewhere down the road I'll look into alternates for those relays using something lower cost (if possible). For now, it is what it is.

As I said, I ended up ordering from DigiKey and have a shared cart you can order from here. You'll be presented with some options because some of the parts are cheaper per unit if you order a higher quantity. If you want spare parts go for it, otherwise just keep the BOM specified amounts.

At the end of all of this, if the project works, I'll contribute all of this back to the Github project so it's current to 2018. Remember, don't commit non-working stuff.

With that part done it's time to start on the firmware development environment for the PIC16 controller using the MPLAB-X IDE development environment.
