Removing through-hole variant

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

Looking at the SMD board, there are still 9 components which require hand-soldering, for a total of 38 solder points. Still less than a 40pin RPi header haha ;)

This made me wonder if the through-hole board variant is even necessary. As it turns out, there's no real difference between the two, other than "a bunch of passives to hand-solder".

With that in mind, and for simplicity's sake, I've decided to only offer 2 variants:

Once the boards arrive, I'll post instructions for those who want to source the components on their own.

I considered using an SMD component for the RS-485 IC, but I think a few people might want to choose an alternative IC, such as a slew-rate limited device or something similar. In that case i'd rather provide more generic boards which accept a standard 8-pin DIP socket.
