• PCBs lessons learned

  The good:

  - PCB shapes turned out to be good. The PCB was scanned then vectorised and then imported to EAGLE. This process worked out fair enough.
  
  

  The bad:
  

  - The footprint of the salvaged pushbutton is small (damn I have skipped the always verify footprints on a printout before PCB ordering) Using multiple device footprints in these cases usually a positive thing.
  

  - Always add more info on the silkscreen if possible: having the USB coloring present would have been helpful

  - When making single boards like the RJ50 side make it universal: I should have broke out all the 10 RJ50 pins to pinheaders, then it could have been repurposed for other things in the future.

  - The ESD protection TVS was not at hand instead I populated NUP4302. However that part does not have connection between the in and out pins. Some extra green wiring was necessary.
  
  

  The lucky:

  - There were some DRC errors: the beeper pad overlapped with one connector pad.Luckily the connector pad was not connected to anywhere.
  
  

• PCBs arrived

  I fitted one PCB set to my last dirtyPCBs order, and received them:

  As you see I made two separate PCBs to spare board space.

  The RJ50 and main boards will be connected with a blank PCB strip:
