The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). 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.

Description

Arduino NANO:-

Arduino NANO is the open source smallest Embedded Development board launched by Arduino based on Atmega328 SMD Package Microcontroller. It is a Surface mount Breadboard Friendly board integrated with Mini USB Port. DC Power Jack is not available on this Board, so power can be given through Mini USB Cable. It automatically sense and switch to the higher potential source of power, there is no need for the power select jumper.

Arduino Nano Pinout Configuration

Pin Category	Pin Name	Details
Power	Vin, 3.3V, 5V, GND	Vin: Input voltage to Arduino when using an external power source (6-12V). 5V: Regulated power supply used to power microcontroller and other components on the board. 3.3V: 3.3V supply generated by on-board voltage regulator. Maximum current draw is 50mA. GND: Ground pins.
Reset	Reset	Resets the microcontroller.
Analog Pins	A0 – A7	Used to measure analog voltage in the range of 0-5V
Input/Output Pins	Digital Pins D0 – D13	Can be used as input or output pins. 0V (low) and 5V (high)
Serial	Rx,Tx	Used to receive and transmit TTL serial data.
External Interrupts	2, 3	To trigger an interrupt.
PWM	3, 5, 6, 9, 11	Provides 8-bit PWM output.
SPI	10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK)	Used for SPI communication.
Inbuilt LED	13	To turn on the inbuilt LED.
IIC	A4 (SDA), A5 (SCA)	Used for TWI communication.
AREF	AREF	To provide a reference voltage for input voltage.

Serial Communication Pins

Pins – 1, 2 1 – RX and 2 – TX

These two pins RX- receive and TX- transmit are used for TTL serial data communication. The pins RX and TX are connected to the corresponding pins of the USB-to-TTL Serial chip.

PWM Pins

Pins – 6, 8, 9, 12, 13, and 14

Each of these digital pins provide a Pulse Width Modulation signal of 8-bit resolution. The PWM signal can be generated using analogWrite () function.

Arduino Nano ICSP

ICSP stands for In Circuit Serial Programming, which represents one of the several methods available for programming Arduino boards. Ordinarily, an Arduino bootloader program is used to program an Arduino board, but if the bootloader is missing or damaged, ICSP can be used instead. ICSP can be used to restore a missing or damaged bootloader.

Each ICSP pin usually is cross-connected to another Arduino pin with the same name or function. For example, MISO on Nano’s ICSP header is connected to MISO / digital pin 12 (Pin 15); MOSI on the ISCP header is connected to MOSI / digital pin 11 (Pin 16); and so forth. Note, MISO, MOSI, and SCK pins taken together make up most of an SPI interface.

We can use one Arduino to program another Arduino using this ICSP.

GND	GND
MOSI/D11	D11
MISO/D12	D12
SCK/D13	D13
D10	Reset

SPI Pins

Pins - 13, 14, 15, and 16

When you don’t want the data to be transmitted asynchronously you can use these Serial Peripheral Interface pins. These pins support synchronous communication with SCK as the synchronizing clock. Even though the hardware has this feature, the Arduino software doesn’t have this by default. So you have to include a library called SPI Library for using this feature
