|
the primary route that I took for homework is taking a business model Programmer AVR and modify, in this case I took a design from Sparkfun, they giving us a design of their PCBs,I had a similarity with the model proposed to develop and I also liked the design by the USB port |
|
This is the complete PCB layout I downloaded from Sparkfun, I found connectors and extensions were missing and others that I consider not use, so I proceeded to edit |
|
After removing the components that I will not use and eliminating the tracks that you had routed this was my design this alone was routed tracks |
|
After routing only in the top layer and to customize my design, I had everything ready to use models; The steps I did for this were Export from Eagle to 450 dpi resolution, a monochrome image format PNG Bring to fabmodules to send to the models |
|
|
|
 |
|
After having my design finished was ready for welding, however the problem I found was that I did not have all the necessary to implement componenetes, values were commercial but not had in inventory FabLab, so I had to make another design |
|
I took the proposed design since this was in the certainty that I would not be lacking components, I made the extraction of the design to do mine |
|
HI implemented the circuit schematic in Eagle, with the necessary connections to generate PCB design |
|
I created my file PCB perform the routes as in my previous model, personalize, and we had everything ready to mill my circuit design. |
|
Recalling the previous steps and with the same parameters obtained my design on the copper plate,Before welding perform a visual check of good tracks on the PCB, then perform a review with the Multimeter ,After finishing welding this is my final design with all my components |
|
To test the proper operation of the plate, it was necessary to connect the AVRISP ATMEL and that recognizes, in this case the green led indicates no problem |

Programing the FABISP:1.-for ISP programming on Ubuntu I had to download drivers and software 2.-Then download the firmware FABISP 3.-after thatEverything works right 4.-then Make a point HEX 5.-All were OK design files ( DOWNLOAD ) |
