DIY Arduino Nano

The Arduino Nano is a small & breadboard-friendly based on the ATmega328P Chip. It has more or less the same functionality of the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.

I would like to Thank Arduino for their contributions to the community and a huge Thanks for keeping it Opensource.

Now the actual Arduino nano utilities Atmega328p-AU chip which is comes in SMD package. Smd components are hard to solder with a regular soldering Iron. So I want to use THT version of the same IC in my project. It's easy to use.

We also need some passive components to make the IC up and running. Such as 16MHz Crystal oscillator and two 22pf capacitor. and we also need a 10k resistor to pull up the reset pin of the IC. and some decoupling capacitors at the input power source.

The final Schematic will look something like this

I also use some header Pins to be able to program my board using a FTDI to Serial programmer like this

The connection will be as follows,

So there you have it guys your own DIY arduino nano.
