Ordered new PCBs (v02)

A project log for ╬╝Diff: Long distance digital signals over RJ45

A simple 50mmx44mm module to route power and differential signals (RS-485) over RJ-45

The v02 PCBs have been ordered for the through-hole variant (and I updated all the pictures for this project).

This version is much better than v01 and fixes some trace issues. Now every track is minimum 0.5mm and the power traces are 1mm which can (theoretically) handle ~2.3A of current. That could be useful for those who wish to upgrade the voltage regulator to output more current (eg: 5V@2A). In that case a larger fuse will also be needed.

The board is now much smaller as well, instead of 64mm x 46mm, I got it down to 50mm x 44mm, and rounded the corners and added some grounded M3 holes in the corners.

Finally, I added a few personal touches to the soldermask, including more useful information for soldering.

I'm looking forward to seeing how these boards turn out.

I plan on finalizing the SMD board within the next week.
