EAGLE (for: Easily Applicable Graphical Layout Editor, German: Einfach anzuwendender grafischer Layout-Editor) by CadSoft Computer is a flexible, expandable and scriptable EDA application with schematic capture editor, PCB layout editor, auto-router and CAM and BOM tools developed by CadSoft Computer GmbH, Germany, since 1988.

EAGLE is popular among smaller design houses and in academia for its favourable licensing terms and rich availability of component libraries on the web.[citation needed] Hobbyists are attracted by the availability of freeware licenses.[citation needed]


EAGLE was developed in 1988 as a 16-bit application for Microsoft DOS, with support for OS/2 and Windows added later on. Starting with version 4.0, EAGLE was converted to 32-bit. EAGLE version 4.0 also dropped support for DOS and OS/2, but was among the first professional electronic CAD tools available for Linux. A 32-bit DPMI version of EAGLE 4.0 running under DOS was available on special request in order to help support existing customers, but was not released commercially.

Starting with version 4.13, EAGLE became available for Mac OS X, with versions before 5.0.0 still requiring X11. Version 5.0.0 officially dropped support for Windows 9x and Windows NT 3.x/4.x. EAGLE 6.0.0 no longer supports Mac OS X on the Power PC platform (only on Intel Macs), and the minimum requirements have been changed to Mac OS X 10.6, Linux 2.6 and Windows XP.

On 24 September 2009 Premier Farnell announced the acquisition of CadSoft Computer GmbH, developer of EAGLE.[1]

Schematic capture[edit]

EAGLE contains a schematic editor, for designing circuit diagrams. Parts can be placed on many sheets and connected together through ports.

PCB layout[edit]

The PCB layout editor allows back annotation to the schematic and auto-routing to automatically connect traces based on the connections defined in the schematic.

EAGLE saves Gerber and PostScript layout files and Excellon and Sieb & Meyer drill files. These standard files are accepted by many PCB fabrication companies.

Notable users[edit]

Popular DIY electronics site SparkFun uses EAGLE, and releases the EAGLE files for boards designed in-house. Other popular sites/products that use EAGLE include Adafruit, Arduino[2] and Dangerous Prototypes.

Third-party libraries[edit]

Of particular note is the popular DIY electronics parts store SparkFun Electronics[3] that has grown up largely due to the hobbyist market exemplified by Make magazine and others. Many of these companies offer EAGLE part libraries[4] which define schematic shapes, pinouts, and part sizes to allow for correct layout in the PCB layout editor. Other popular libraries include Adafruit[5] and Dangerous prototypes,[6] element14 (a subsidiary of Farnell, owners of CadSoft) also have some libraries available from their site.[7]

Beginner usage[edit]

A large group of tutorials exists for beginners to design their own PCBs.[8][9]
