I designed a PCB. What''s wrong with it?

Hello from Gregg C Levine
Nothing that I could see, on first glance. If you can work on that
board, without causing damage to it, then your okay.
Suppose you post a few more details. Like an idea behind what your
planning on doing with this Maxim part. And have you successfully
bread-boarded this circuit first? It's my guess that you have done
that step, that's why you went to the next step that of creating a
PCB. Have you had a chance to try it? Does it work? What happened?
What does the code for it look like?
