Week 6: electronics design

At this week we shoud to design our personal HelloWorld board using Eagle.

I`m still working on my personal MacBook, so i installed Eagle and all libraries on it.

You can find Eagle here: http://www.cadsoftusa.com/downloads/

Next thing you need is a components library:

In this helloEcho folder you also find an example files, which is easy to start. On example scheme already is

• 6-pin programming header
• microcontroller: attiny44A
• FTDI header
• 20MHz resonator

 

We need to add:

• Resistors (10K and 499 Ohms)
• Button
• Ground
• VCC
• LED

 

Button should be connected to pin 10. LED - to pin 6.

Here is the board i designed:

 

 

 

 

I've never worked in Eagle, but it was easy enough. Most of the time spent on the optimization of the traces.

 As a result I got:
