Hi....
So this is my first eagle library EVER and its also my first post EVER where i share something that i have created.
Background:
I am making a circuit for one of my projects and i needed a footprint that matched the arduino nano...
After a LOT of googling i came up empty handed....
So what did i do????
I tried to make one myself of course 
And here are the results in eagle schematics and board editor:

I hope that some of you will find this useful 
BTW: I dont know how to remove the pin names (P$1, P$2...) So deal with it or edit my design and upload your fixed version
Copy rights:
This desing is under the copy right "Do what the f*** you want with it" So becareful...
-Edit
If you see any faults please let me know
