Eagle CAD libraies

I can only strongly recommend to draw your own libraries.

I found that downloaded libraries often contain errors and if they don't they often don't adhere to the rules for text placement (use name layer instead of docu layer) which may mess up the silk screen.

Anyway, if you use downloaded libraries check them at least twice. There's no fun when pins are swapped or the clearance is too small and the part won't fit in the final pcb.
