This is a regular arduino board which contains extra features such as an extra VCC/GND rail and it uses an ATmega 328p SMD which has 2 extra analog pins (A6 - A7) . All you need to do is solder the components and use a (FT232RL) USB to TTL converter to upload a code. If you don't have this converter , you can simply follow the procedures below.

you will need: ATmega328p(SMD) ,220ohm resistor(SMD) ,SMD LED (4),16MHz crystal,  pushbutton switch, (FT232RL) USB to TTL conveter, LM7805 (SMD) ,AMS 1117 (3.3V), female pin headers, a lot of lead.

In case u don't have a (FT232RL) USB to TTL conveter simply follow these steps,

• first take a regular arduino UNO board and REMOVE it's micro controller(ATmega328p).

• Then make these connections,

• after making the connections, simply go to the arduino IDE and upload a sketch.

• for more info about the connections click the link below.
