Well my boards came in today and the holes were too small for the legs
on the connector :/ I know you already ordered a set, so, sorry about that.
However I was still able to solder one together anyway and verify that
electrically it works. If you use flux, the solder will wick down the
hole and wet onto the pin well even though you're heating and adding
solder only from the other side of the board.

No worries Brian. Consider me your alpha tester when you get it
finished though, I'll order it and let you know how things turn out.

Don't rush to actually order this one just yet! I think I made the
holes
too small for the through-hole connector. I forgot I was supposed to
check the actual connector before finishing up.
