Libraries (.lbr files) store the individual parts that you add to your board. When you close it, all windows that it opened get closed as well.Ī description of the various categories in the Control Panel: The control panel is the main window of Eagle. On Schematics, parts are laid out where they make sense electrically, on Boards, they are laid out where they physically make sense, thus a resistor that is right next to a part in the Schematic may end up as far away from that part as possible in the Board. Only in Board layout does it matter where the parts physically go.

Note that the Schematic's job is only to define the parts and the connections between them. It defines the parts you have in your project, and which pins on the parts should be connected.īoard - This is where you lay out the pieces of your project and physically connect the correct pins as defined in the Schematic. Schematic - This is where you draw the schematic for your project. Advanced usage of this will not be covered in this tutorial Library - Allows you to manage and edit parts. When used properly, this allows you to work very rapidly, but it can also be a major source of aggravation if you are used to the Windows-y way of doing things.Įagle has four basic views: Library, Schematic, Board, and Control Panel.Ĭontrol Panel is the main window, it launches everything else and when you close it, all subordinate windows get closed. That is, you select one mode, perform it a bunch of times, as opposed to selecting an object and applying an single operation at a time. Eagle's UI is designed with what is called a modal interface.
