Introduction to arduino nano every, arduino nano every pinout, arduino nano every features, arduino nano every applications
Hi Guys! I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to Arduino Nano Every. Arduino Nano Every is a tiny powerful board that is based on the ATMega4809 AVR processor. It comes with a clock speed of around 20MHz and flash memory of around 48KB. It carries two 15 pin connectors on each side of the board that are pin-pin compatible with the Arduino Nano Every. The low price and small size make this board an ideal pick for the range of electrical projects like electronic musical instruments, low-cost robots, and general development of the small parts of the large projects. Needless to say, Arduino has been a cornerstone of many electronic projects ranging from simple student projects to complex automation and embedded projects. The working of this tiny beast is simple and straightforward. It takes the input like a finger on a button or light on a sensor and converts it into an output like turning on the motor, activating LED blinking, and something sharing online. You can use Arduino IDE software to program the Arduino board. In other words, you can control the board by sending a lot of instructions to the microcontroller of the board. The Arduino comes with easy to use hardware and software platform that even a non-tech person can get a hands-on experience without having prior technical knowledge about these boards. I suggest you read this post till the end as I’ll walk you through the complete Introduction to Arduino Nano Every covering datasheet, pinout, pin description, features, and applications. Let’s get started.

Introduction to Arduino Nano Every

  • Arduino Nano Every is a tiny powerful board that is based on the ATMega4809 AVR processor.
  • The Arduino Nano Every is almost similar to the Arduino Nano board with the addition of a more powerful processor like Atmega4809.
  • This board comes with more program memory compared to Arduino Uno and RAM is 200% bigger, helping you create a lot of variables.
  • If you’ve used Arduino Nano earlier for your project, you’ll come to know the Arduino Nano Every board is a pin-equivalent substitute of Arduino Nano. The difference lies in the addition of a micro-USB connector and a more powerful processor.

  • Arduino Nano Every is available in two versions: with or without headers, helping you incorporate this board into hard-to-reach places including wearables.
  • No components are available on the B-side, this gives you the ability to solder the board directly into your main PCB design, reducing the height of the entire project.
  • It carries a crystal oscillator with a clock speed of around 20MHz which is necessary to synchronize all internal functions of the board.
  • The SRAM memory is 6KB while the flash memory and EEPROM memories are 48KB and 256bytes respectively.
  • The flash memory is the location where the Arduino program (sketch) is stored. While SRAM is used to generate and manipulate variables when it starts running. And the EEPROM is a non-volatile memory which means data stays stored inside the board even if the board power is removed.

Arduino Nano Every Datasheet

While working with this board, it’s better to look into the datasheet of the board that features the main characteristics of the board. Click the link below to download the datasheet of Arduino Nano Every.

  There is a built-in LED at pin 13 and it also features one power LED that turns on when the board is supplied with power.

Arduino Nano Every Pin Description

Still reading? Perfect. I hope you’ve read the brief intro of this Every board. In this section, we’ll highlight the description of each pin incorporated on the board. Let’s get started.

Digital Pins

20 digital I/O pins are incorporated on this device which you can use as an input or output based on the requirements. These pins are either in a HIGH state or LOW state. When they are LOW they receive V0 and when they are HIGH they receive 5V.

Analog Pins

The number of analog pins incorporated on the board is 8. These are analog pins which projects they can receive any number of values in contrast to Digital pins that only receive two values i.e. HIGH or LOW

PWM Pins

The number of PWM pins incorporated on the board is 5. The board creates analog results with digital means when these pins are activated.

I2C Pins

This board incorporates a two-wire communication protocol which is known as I2C protocol. It carries two lines i.e. SCL and SDA.

The SCL is a serial clock line mainly used for the synchronization of all data transfer through the I2C bus and the SDA is a serial data line mainly used to carry the data.

SPI Pins

This device comes with SPI (serial peripheral interface) pins that are mainly used to lay out the communication between the controller and other peripheral devices such as sensors or shift registers. There are two pins: MISO (Master Input Slave Output) and MOSI (Master Output Slave Input) used for SPI communication. These pins are employed to receive or send data by the controller.


The UART pins are used for serial communication. It carries two lines Tx and Rx. The Tx is used to transmit the serial data while Rx is used to receive the serial data.

Arduino Nano Every Features

The following are the main features of Arduino Nano Every. Operating Voltage = 5V Microcontroller = Atmega4809 Vin range = 7 to 21 V D/C current per 3.3V pin = 50mA D/C current per I/O pin = 20mA Oscillator = 20MHz EEPROM = 256bytes SRAM = 6KB Flash Memory = 48KB LED_BUILTIN = 13 USB = 1 UART = 1 SPI = 1 I2C = 1 Digital Pins = 20 Analog Pins = 8 PWM pins = 5 Size = 18x45 mm Weight = 5g


  • Arduino IDE (integrated development environment) is used to program this board. This software is used to program all kinds of Arduino boards.
  • This device contains a built-in Bootloader which is used to burn the program inside the controller. Yes, you don’t need a separate burner to burn and transfer the program into the controller.
  • Moreover, it also carries a micro USB port which is used to connect the device with the computer. Using this port, you can test and run the program directly from the computer.

Difference between Arduino Nano Every and Arduino Nano

  • The Nano carries microcontroller ATmega 328p which is the same as Uno.
  • While the Nano Every and Uno WiFi Rev 2 are incorporated with a modern version of the AVR based MCU known as megaAVR_0-series, an ATmega4809.
  • It carries the same AVR CPU architecture in the base of the MCU so initially, both MCUs (Atmega 328p and Atmega 4809) share the same compiler but there lies a difference in MCU peripherals configuration. So know that the previous knowledge about AVR MCU peripherals won’t help here.
  • The Arduino Nano Every is priced lower than Arduino Nano.

Arduino Nano Every Applications

The small size of this board makes it a good pick for a number of applications. Following are some applications of this board.
  • USB Trackpad
  • Automatic Pill Dispenser
  • USB Joystick
  • Electric Bike
  • Creating a wireless keyboard
  • Water Level Meter
