Autodesk EAGLE

CadSoft EAGLE is proprietary EDA (electronic design automation) software for editing circuit schematics, PCB layouts and component libraries. It is available for Windows, Linux and OS X. EAGLE is quirky and initially unintuitive, but very widely supported and stable.

Editions
The Light edition can be used for free, for non-profit or evaluation. This is limited to boards of 100 x 80 mm (4 x 3.2 inches), only top and bottom signal layers, and the schematic editor can only create one sheet. It can however Load, view and print drawings that exceed these limits.

For a single user doing non-commercial editing of e.g. the most commonly used Eurocard size, would require the Hobbyist edition, which costs €140. This allows boards of 100 x 160 mm (4 x 6.4 inches), up to 99 sheets and up to 6 signal layers. For commercial use, with the same limitations the Standard edition costs €690.

Edit features
With almost identical user interfaces EAGLE provides a schematic editor, a layout editor, and library editor.

Compatibility
EAGLE exports Gerber files.

In 2009 CadSoft Computer GmbH, developer of EAGLE was aqquired by Premier Farnell. Since version 5.11 EAGLE connects to the components database from Premier Farnell (also known as Farnell, Newark, element14), allowing immediate access to component information from within the design environment.
