• At that place is one limitation of using Arduino Nano i.e. it doesn't come with a DC power jack , which means you tin not supply an external ability source through a battery.
• This board doesn't use standard USB for connectedness with a computer, instead, information technology comes with Type-B Micro USB .
• The tiny size and breadboard-friendly nature make this device an ideal option for most applications where the size of the electronic components is of great concern.
• Flash retentivity is 16KB or 32KB that all depends on the Atmega lath i.e Atmega168 comes with 16KB of flash memory while Atmega328 comes with a flash memory of 32KB. Flash memory is used for storing code. The 2KB of memory out of total wink memory is used for a bootloader.
• The SRAM memory of 2KB is present in Arduino Nano.
• Arduino Nano has an EEPROM memory of 1KB .
• You can download Arduino Nano Datasheet by clicking the below push:

Download Arduino Nano Datasheet

• The post-obit figure shows the specifications of the Arduino Nano board.

• Information technology is programmed using Arduino IDE which is an Integrated Evolution Environment that runs both offline and online.
• No prior arrangements are required to run the board. All y'all demand is a board, mini USB cable and Arduino IDE software installed on the calculator.
• USB cable is used to transfer the program from the computer to the board.
• No separate burner is required to compile and burn the programme every bit this board comes with a built-in boot-loader.

Now, allow's have a await at Arduino Nano Pinout in detail:

Arduino Nano Pinout

• The following figure shows the pinout of the Arduino Nano Board:

• Each pin on the Nano board comes with a specific office associated with it.
• Nosotros can see the analog pins that can be used as an analog to a digital converter, where A4 and A5 pins can also exist used for I2C communication.
• Similarly, there are fourteen digital pins, out of which vi pins are used for generating PWM.

Allow'due south have a wait at the Arduino Nano Pinout in detail:

Arduino Nano Power Pins

• Vin: Information technology is input power supply voltage to the lath when using an external ability source of 7 to 12 V.

• 5V: It is a regulated power supply voltage of the lath that is used to power the controller and other components placed on the lath.

• 3V3: This is a minimum voltage generated by the voltage regulator on the nano board.

• GND Pin: These are the ground pins on the board.
• In that location are multiple basis pins on the board that can be interfaced appropriately when more than one basis pin is required.

Arduino Nano Office Pins

• Reset Pivot: Arduino Nano has two reset pins incorporated on the lath, making any of these Reset pins LOW volition reset the microcontroller.

• Pin#13: A built-in LED is continued to pivot#13 of nano board.
• This LED is used to cheque the lath i.e. it'southward working fine or not.
• AREF: This pin is used as a reference voltage for the input voltage.

Arduino Nano I/O Pins

• SPI Protocol: 4 pins 10(SS->Slave Select), eleven(MOSI -> Chief Out Slave In), 12(MISO -> Master In Slave Out) and 13(SCK -> Series Clock) are used for SPI (Serial Peripheral Interface) Protocol.
• SPI is an interface bus and is mainly used to transfer data between microcontrollers and other peripherals like sensors, registers, and SD cards.
• I2C Protocol: I2C communication is developed using A4 and A5 pins, where A4 represents the serial data line (SDA) which carries the data and A5 represents the serial clock line (SCL) which is a clock signal, generated past the master device, used for data synchronization betwixt the devices on an I2C bus.

Arduino Nano Programming & Communication

• The Nano lath comes with the ability to prepare communication with other controllers and computers.

• Arduino board software is equally compatible with Windows, Linux or MAC, even so, Windows are preferred to utilize.

Arduino Uno Vs Arduino Nano

• Both Arduino Uno and Arduino Nano come with the same functionality with little difference in terms of PCB layout, size and class cistron.
• Arduino Uno is a microcontroller board based on Atmega328 and comes with fourteen digital I/O pins out of which half-dozen are PWM. At that place are 6 analog pins incorporated on the lath. This board comes with everything required to support the microcontroller like a USB connection, a Power jack, 16MHz oscillator, reset button and ICSP header. Yous don't require an extra peripheral with the board to go far work for automation.
• Information technology is a complete prepare to use device that requires no prior technical skills to go hands-on feel with it. You can power it by using a DC power jack, battery or simply plug it into the computer using a USB cable to get started.
• Arduino Nano is modest and compact as compared to Arduino Uno. It lacks the DC power jack and comes with Mini USB support instead of regular USB. Besides, the Nano lath comes with two extra analog pins i.e. 8 pins as compared to vi analog pins in the Uno board. Nano board is breadboard friendly while Uno board lacks this property.
• However, both devices run at 5V, come with a current rating of 40mA, and 16MHz of the clock frequency.

Arduino Nano is a very useful device that comes with a wide range of applications and covers less space as compared to other Arduino boards. Breadboard-friendly nature makes it stand up out from other boards. Following are the main applications of Arduino Nano:

• Engineering Students' Projects.
• Medical Instruments
• Industrial Automation
• Android Applications
• GSM Based Projects
• Embedded Systems
• Automation and Robotics
• Dwelling house Automation and Defense Systems
