Electronics design
This week we had to redraw the echo hello-world board. I used the great Tutorial by anna kaziunas. First I downloaded the EAGLE program and downloaded the board Schematic and copy it to the project files. then I dawnloded the libaries. After that I copied them to the lbr folder in the eagle program and opened eagle to add the required components(button and led).![](img/egl.jpg)

To prepare the board for milling you need to select only the top layer, and export the file as png (do not forget to chose MONOCHROME and 500 PDI).
