Well, I received the PCBs today but it seems there was a manufacturing error. Everything is flipped/mirrored... Here's how the top layer looks like... the bottom layer is also flipped/mirrored.

BUMMER!



I sent this picture to the manufacturer along with what the Eagle board is supposed to look like. I emailed them... and within a couple of hours, I got a call from them on the phone apologizing for the mistake and they found out where in their process they had the mistake... they're going to remanufacture my boards and resend them to me at no charge!  Talk about great service!  The quality of the boards and it's workmanship do look very nice too, and their prices are great.

This is my first order from them, and even if they did screwed this up, I think I'll use them in the future. I like how they handled the problem very well and took steps to correct it.

I'll keep you guys updated about the progress.
