Have you put together an Arduino-based circuit and looking to nicely (but easily) document it? Or perhaps you're looking to create an Arduino Shield with EAGLE and want to start with the correct dimensions of the headers. Element14 has come to the rescue with the Arduino library of EAGLE parts for exactly that. There are two types of components in this library: the standard version with a PCB footprint showing the key connections and the 'EXT version which has no PCB footprint.
The Standard version will be great for those looking to create a shield or want to somehow integrate the Arduino somewhere on another PCB. While the EXT version allows people to create a schematic that doesn't bother with a PCB. In the EXT case, the user can create a PCB that is intended to connect to an Arduino via cables that are shown on the schematic, but isn't included on the PCB.
Faster documentation, easier creations!
