I finally ordered the v.05 PCBs after making one final change:

Rather than connecting the 8P8C connector shield pins to GND, I tied them to "Earth" which is tied to the M2 mounting hole (H2) right behind the 8P8C connector. I also added another solder bridge jumper (JP3) which would allow you to tie "Earth" and GND together.

The idea is the PCB, when mounted in an enclosure, can be tied directly to real "Earth" through one of the mounting holes. Wiring the 8P8C shield to that is also a good idea, to reduce EMI radiating from the RJ45 cable. In many cases it would be important to also tie the PCB ground (GND) to "Earth", but I wanted to leave that optional, so I added the solder bridge jumper (JP3).

I should receive these boards in ~2-3 weeks depending on the weather (it's typhoon season here in East Asia). As usual, once I receive them i'll run some tests and confirm everything before making them available on Tindie.

Stay tuned!
