Drawing the Board

1.To draw the board we downloaded Eagle.

2.Import a parts library from the FabAcademy schedule page for this week

3.To place the library in Eagle save the link to the folder Eagle makes under MyDocuments. It will then show up in the PROJECT folder under EAGLE

4.To make things simpler hide all the libraries not in use. Right click on the LIBRARIES folder and choose USE NONE. In this case we will using the SUPPLY.LBR so make that active by making the dot green. The FAB.LBR should also be green.
