Which software do you use for components and page layout design ?

Hello,

The board and components illustration, and the starter book are simple, clear and beautiful.

I'm wondering how you have achieved such impressive result as I would like to offer the same level of quality for educational and tutorial books/webpage for our arduino-based projects.

Can you tell me which software do you use for your components illustrations and the page layout of your books?

Thanks !

Fritzing is a popular choice for those "photo-like" pictures, and Eagle is often used for good schematics.

Thanks for the hint, yet we have a custom board (fork of Due) made with KiCad.
It is not clear for me if is it possible to create a custom board illustration with Fritzing or if it only embed the official ones ?

I think it's possible to create custom components for Fritzing, but I have no idea how.....

Yes Fritzing is the best one I have found! Also includes Arduino now!
