Download and install Eagle

Linux 64-bit

Eagle requires a 32-bit environment which may or may not be installed in linux yet.
I have taken the step to istall the following libraries prior to running the eagle.run file from here

sudo apt-get install ia32-libs lib32z1 lib32z1-de

After this eagle installed without a problem.

Linux alt-click / alt-drag moving the window problem

The newer Linux window managers tend to use the alt-click or alt-drag combinations to move or re-size windows. This prevents us from using that same key in both Blender and Eagle.

tip about using alt-grid on ubuntu:

but also look into changing this behavior from the regular window manager. (as it is apparently not a keyboard shortcut...)

For Linux Mint 17, the following trick was used:

Designing circuits with Eagle


Open Eagle

  • Select New Project
  • Select New Schematic

Open library turn off all libraries, right click use none: scroll down to supply enable

  • fab.lbr
  • supply1.lbr
  • rcl.lbr
  • led.lbr
  • v-reg.lbr
  • Open library, click Use
  • Download from the internet a library or select on in the computer the library that we will be using (e.g.
  • fab.lbr[1]
  • SelectAdd, then you can open the library
    • (if you don't find your thing you could also click on "Use")

Tour for the Eagle on CadSoft site


Starting new projects

  • File -> New Project
  • File -> New Schematic
  • File -> Save As (filename.sch)
  • Select the things you want to use and click Add to get the components.
  • You can select different view by clicking on Board
  • You can select object by right clicking them and selecting packning
  • Connect objects by clicking Wire and make wire between objects.
  • It can be good to make connections and get a sign for Ground and put where it should be GND.

Board view

  • View Grid select the size of the grid, alternative grid could be around (0,025 inches)
  • Move to move object or line.
  • Delete to remove object or line and so on.
  • Junction Connection point .
  • Ratsnest Calculates calculate the airwires so that they show the shortest possible connections.
    • You can right click objects and select value to set values e.g. for capacitors or resistors
    • Right click on object and select properties to rename.
    • You can check out if you have connected the object by moving them.
  • ERC Electrical rule check, search for errors.

Arrange objects

A tip for arranging objects

  • Start with data signals, and do your power signals (GND and VCC the last).


Check the design rules.

  • Tools ->DRC -> Load-> Check
  • Frame to make frame around the design.
  • Arrange objects
  • click Auto
    • Select Bottom N/A

If it is not as good as you wanted you can select lines, by right clicking them and select rip off

View-> Layer settings ->

  • All ->Ok ( to check out if everything is within the board, also the layers that are not visible.
  • None ->

and the turn on the layers you want to have.

  • File -> Export image
    • resolution: 1200 dpi
    • Area: Full
  • Monochrome: check.

Info about Circuits

  • TX transmit
  • DTR data terminal ready
  • Rx Recieve
  • Miso -master in slave out
  • Mosi master out slave in
  • sck system clock
  • MOSI (3) GND (2) MISO (1) |
  • -RESET (4) SCK (5)

Project 1

  • First project could be to make schematic of this board and to add something to it, add (at least) a button and LED (with current-limiting resistor) to the serial echo hello-world board, check the design rules, and make it

Materials used

  • IC1 = ATtiny44_SOIC('IC1\nt44') -> see in fab.lbr
  • R1 = R_1206('R1\n10k') -> See in fab.lbr
  • C1 = C_1206('C1\n1uF') -> fab.lbr
  • XTAL = Crystal 20 MHz -> search for crystal in fab.lbr
  • FTDI connector (6 pin) ->search for ftdi in fab.lbr
  • Header (2*3 pin) -> search for isp in fab.lbr
