On this page, I will introduce the example which creates the mask pattern of the printed board automatically with EAGLE. The purpose of this example is the experience of creating a schematic and drawing a pattern automatically with the created schematic. So, as for the various setting, a default is used.
The circuit to use is "A-stable multivibrator (IC type)" to be introducing on another page. Before, I created the printed wiring of this circuit by handwriting.
