Discription- 

This board is fully compatible with Arduino Nano. It is based on the ATmega328p-AU from the atmel, the SMD version of one used in Arduino Uno. The advantage of this module, is that is very small in size as compared to Arduino Uno. It has integrated USB, and is breadboard friendly. It does not have any power jack, but still senses, and switch to higher potential power source.

Arduino Nano can be said to be a smaller version of Arduino Uno, as its using the same MCU with smaller package. It also provides same functions as provided by Arduino Uno. Apart from that, it has 8 analog input pins instead of 6 analog inputs in Arduino Uno. It also has pinout for the programmer to be connected to the board directly, in case USB is not used for programming. It also has 1 x USART, 1 x SPI, 1 x I2C peripherals.
