+In [[lab_4]] we drew the schematic of our board. Now let's do the layout of our PCB. We'll use the layout part of Eagle, along with perhaps the footprint editor and autorouter.  This will conclude our exercises with PCB design; after this we'll move on [[dig:#schedule|to logic design with FPGAs]].
 Using the {{dig:micboard-v0.zip|micboard.zip schematic}} (or your own schematic if you think is is better or more complete), turn your schematic into a daughterboard for the AVR32 bronze board. Please observe the following points:

   - Keep sensitive electrical nodes far away from the noisy digital servo control.

 You may find it helpful to again scan the {{dig:eagle_manual_en.pdf|Eagle manual}} and tutoral ({{dig:eagle_tutorial_en.pdf|en}} {{dig:eagle_tutorial_de.pdf|de}}).  You might also find it helpful to open the integrated help in Eagle, for instance while routing wires (ROUTE). The help shows you which mouse button and keys places vias, changes wire direction, changes layers, etc.

 When you are finished with your board schematic and layout, send a zip/tgz archive of your design to [[tobi@ini.phys.ethz.ch?subject=micboard design for Electronics for Physicists II]]
