Arduino DDS VFO

So version 1 of these boards was a bit of a failure, a couple of minors errors in missing tracks, and a major one in super failure of how the buffer amp was laid out. The minor errors are ones i can live with for my own projects, but the bad design of the buffer is a bit of a killer. Anyway its the first time i have manufactured a board, so failure is always an option.

I have a work around with them so they are not totally wasted, bypass the buffer and run the DDS direct into the mixer, its close enough to -7dbm output, enough to drive the mixer, I will just have to make sure it does not load down too much. Will see soon as i can pull my finger out and test it.
