I have contacted them already they would also give us a price quote if we send some gerber files of a nearly final design and a BOM so they would also do the assembley.
They also accept Eagle files, so no need for exporting anything.
Currently i am modifying your layout and routing to fit a 4 layer PCB. Acording to my knowledge alls unused IO pins are bound to ground by default so i changed this in your schematic.(please someone verify this).
I just checked: you are right, the default is pull down, pull up or floating is an option. The reason why I thought the default was pull up is the HSWAPEN pin: it enables pull ups during configuration. So during configuration, the choice is between pull up and floating. So there are several options:
- All pins connected to VCCIO:
- Program pull ups in the bitstream: should work nicely.
- Leave bitsream at default pull-down: quite a power consumption during operation (bad choice).
- All pins connected to GND:
- Program pull ups in the bitstream: quite a power consumption during operation (bad choice).
- Leave bitsream at default pull-down: quite a power consumption during configuration.

Saddly i asume there is no way to merge the egale layout files automatic.(this used to be a lot easier with Altium.... I am totaly new to Eagle) And the library of eagle is confusing me over and over again.

As long as the signal names are correct, you can merge files, it is just very cumbersome:
- Open the first file, on the first sheet
- GROUP all
- CUT (0 0)
- Open the second file, create a new sheet or go to the sheet where you want to place stuff.
- PASTE, find a spot to place stuff (e.g. (0 0))
- Save file.
- Repeat for all sheets in the first file.
The above procedure has a minor fault if ICs are spread over more than one sheet (like in my design): once an IC is already present in the design, pasting in more gates of that IC will instead cause a new IC to be instantiated. You need to repair this manually, e.g.:
- For each gate that has the wring IC name:
- DELETE the gate
- INVOKE the gate from the original IC
- Place that gate at the position where the old one was: the connections are made automatically.
