What is Arduino Nano?

Arduino Nano is a small microprocessor which is breadboard-friendly. It was released in 2008 and has 30 male I/O headers with DIP-30 like configuration. DIP means Dual Inline Package. Arduino Nano can be programmed using Arduino Software. It can be powered through a type-B mini-USB cable or from a 9 V battery.

The operating voltage is 5 V and input voltage can vary from 7 to 12 Volts as per the Arduino website. It has a flash memory of 32 KB and a clock speed of 16 MHz. It can communicate with a computer, another Arduino and other microcontrollers. There are 8 Analog IN pins and 22 Digital I/O Pins. It weighs only 7 grams and has a size of 18 x 45 mm.

Arduino Nano controller has been used in Amateur Radio transceivers in addition to numerous other applications. Arduino Nano is open-source hardware! It is used to control antenna rotators as well.
