David Maita's Fab Academy

Objective

-Design and mill an electronic board
-Solder the electronic components
-Program the board
-Show the interaction

Procedure for using the library "fab.lbr"

1 Locate the Fab Academy page (http://fabacademy.org/)

2 Select CLASS ARCHIVE -> 2017-> SCHEDULE-> ELECTRONICS_DESIGN

3 Download and save the library to a folder.

4 Activate the Eagle program and then add the library.

5 I opened a new schematic

6 Then select the ADD option and opened a new Window where we can upload the FAB.lbr library in Manage Lbraries.

7 Then at the end I could use the components of the library of the Fab Academy

DESIGNING A FABDUINO IN EAGLE

1 Run the Eagle Design program

2 Create a new schematic

3 Look for the "Fab" library and select the following files

V_REG_MIC2920
ATMEGA48 / 88/168-AU (ATMEGA48 / 88/168)
JACK-PLUG1 (JACK-PLUG)
6MM_SWITCH6MM_SWITCH (6MM_SWITCH)
LED1206 (LED)
AVRISPSMD (AVRISP)
PINHD-1X6
PINHD-1X4
CRYSTALHC49S (CRYSTAL)
RESISTOR1206 (RESISTOR)
C-US025-024X044 (C-US)

4 Make the component connections in the schematic plane.

5 Generate a Board to be able to order the components and design our Fabduino board.

6 Ordered the components so I could perform the routing of the paths.

7 Then we need to visualize the layers TOP and PADS

8 Then exported the design of my electronic circuit to a PNG file.

9 Name it, resolution of 2400 and we select monochrome.

10 And finally generate my image in png format
