Designing the PCB

Other Hardware 3rd Party Boards

Hello

After using Arduino as an ISP to program my ATtiny I was trying to find which software to use to design my PCB. Any suggestions or any pointers in this regard. On searching I came across certain softwares but is their any criterion of what micro controller is being used etc.

I am new to all this.

thanks

Hi you can't go wrong with eagle cad

Thanks for the reply seadanzig. I was wondering that will its free version allow me to program ATtiny.

Designing a PCB is different function than programming a microcontroller.

You are correct CrossRoads.

Sorry for my typo. What I meant was if it allows to design for ATtiny. I haven't used a PCB design software before but I am assuming that the software will take as an input that which microcontroller is being used in the design.

I was just curious if some one knows that if eagle cad freer version allows that.

Thanks

Yes, eagle can design PCBs for ATTiny mocroprocessors.

PCB CAD software normally has no idea about processors or any other IC. It works with components that you place on the board and arrange according to what makes sense.

All you will need is a component for the schematic capture and a "footprint" for the PCB design. These are readily available for all common components and I would assume the Tiny AVR are easily obtained.

Tutorial series for Eagle CAD

The following limitations apply to the EAGLE Light Edition in general:

The useable board area is limited to 100 x 80 mm (4 x 3.2 inches).
Only two signal layers can be used (Top and Bottom).
The schematic editor can only create one sheet.

You can download AtMega Eagle parts from

if required.

newark.com also has eagle symbols for many parts. Usually about 1/2 of what I am looking for.

avrfreaks link leads to here
"Free Eagle Library with (nearly) all AVR controllers.
You can download the lib on http://www.embedit.de
Visit http://www.embedit.de/content/view/45/26/ for Information about Changes an new Devices"

site is all in German.
Anyone here read German that could download the library and send a copy?
Thanks
Robert
