Looking for example Eagle board file for ATmega2560-16CU CBGA

Other Hardware 3rd Party Boards

Does anybody have an example 2-layer Eagle board file for ATmega2560-16CU CBGA? I would like to design a board with this processor and having trouble getting started.

There are assorted article on BGA breakout in general, I think. Around somewhere.
I think it would be very difficult to put a 100pin BGA on a 2-layer board. (maybe, if you were going to leave a lot of pins "not connected"?)

Yes I am having trouble finding an example, and I would love to find an example specifically with ATmega2560 100 pin BGA if possible. I'm not sure how to get the Eagle part loaded for ATmega2560-16CU. I do plan to leave a lot of the pins not connected.

I don't see a symbol in the Eagle Atmel library, or for download at newark.com. Think you'll have to make one up.

I remember finding an Eagle library for AVR processors that was lacking most DIP packages but had a significant number of surface-mount packages. Maybe one of these:

Cadsoft's AVR library
Adafruit's Eagle library
Sparkfun's Eagle library
AVR Freaks Eagle library

I also remember finding something useful / relevant at element14.com (requires creating an account; no cost). I believe they are the ones that provide individual packages instead of complete libraries. (May have been Newark.)

I vaguely recall Avnet Express (http://avnetexpress.avnet.com/) having some Eagle files.

If I find something on my other computer I will let you know.

The latest version of Eagle uses XML. I found it significantly easier to edit the package / part files using an XML or text editor; Eagle just gets in the way.

Newark is the US "store" for Element14...

editing .xml files directly is an interesting idea. It's certainly provide quicker mechanisms for, say, changing a bunch of pin names...

I remember there being a difference in what resources are available from each. (e.g. One had Eagle files for something I ordered while the other did not. But that could be the thinning hair talking.)

And moving / copying / removing whole packages / parts. Doing the those things in Eagle is tedious (so many clicks; ugh).

And renaming things (search+replace).
