Limitations

The following limitations apply to the EAGLE Light Edition in general:

* The useable board area is limited to 100 x 80 mm (4 x 3.2 inches).
* Only two signal layers can be used (Top and Bottom).
* The schematic editor can only create one sheet.

Apart from these three limitiations the EAGLE Light Edition can do anything the Professional Edition can do. You can even load, view and print drawings that exceed these limits!

The Freeware version of EAGLE Light adds these limitations:

* Support is only available via email or through our forum (no fax or phone support).
* Use is limited to non-profit applications or evaluation purposes.
