#Arduino due vs mega 2560 pinout serial#

The SDL is the serial data pin that carries the data while SCL is the serial clock line that ensures the synchronization of data transfer over I2C bus. The board carries one I2C communication protocol. It contains two Pins… MISO (master input slave output) and MOSI (master output slave input) for the SPI communication. It is used to develop communication between the controller and other peripheral devices like sensors and shift registers. While is a serial peripheral interface communication protocol. The board contains one SPI communication protocol. The Rx is the receiving pin that ensures the receiving of serial data while Tx is the transmission pin that guarantees the transmission of serial data. Each UART serial port comes with two pins Rx and Tx. There are 4 serial ports incorporated on the board. In this section, we’ll highlight the pin description of each pin incorporated on the board. Hope you’ve got a brief idea about this Arduino Mega board. While two LEDs are reserved for Rx and Tx which respond when the serial communication happens on this board. One is a power LED that turns on when the board is turned on. The board incorporates 4 LEDs where one is a built-in LED connected to pin 13 of the board. In the following picture, you’ll see the pinout diagram of Arduino Mega 2560 Rev3. It comes with everything required to support the microcontroller.

More features include a power jack, a USB connection, an ICSP header, and a reset button.

5V and 3.3V which gives the ability to regulate the voltage as per requirements in contrast to Arduino Uno which comes with only one voltage regulator.

This board incorporates two voltage regulators i.e.

This device is also incorporated with a new USB chip (similar to Arduino UNO) - ATmega16U2 (previously ATmega8U2 or FTDI chips were used).

You can say Arduino Mega 2560 is identical to Arduino Uno with more memory and rich I/O interfaces so it is mainly used for more complex and advanced projects.

It is important to note that Arduino Duemilanove/UNO is compatible with Arduino Mega 2560 which projects the shields developed for Duemilanove stands fit for this mega board.

The SRAM is responsible for producing and manipulating the variables when it runs and EEPROM is a non-volatile memory that remains stored in the board even if power is removed.

The Arduino Program (sketch) is stored in the Flash memory which is 256KB and SRAM is 8KB while the EEPROM is 4KB.

The oscillator clock speed is 16MHz which ensures the synchronization of the internal functions.

The operating voltage of the device is 5V while the input voltage ranges from 6V to 20V while the recommended input voltage ranges from 7V to 12V.

The board comes with 4 serial ports, one SPI, and one I2C communication protocol.

There are 15 analog pins incorporated on the board.

There are total 54 digital I/O pins available on the board out of which 15 pins are used as PWM pins.

The Arduino Mega 2560 Rev3 is a microcontroller board that is based on the ATmega2560 microcontroller.

I suggest you buckle up and read this entire post till the end as I’ll detail the complete Introduction to Arduino Mega 2560 Rev3 covering pinout, pin description, features, programming, and applications. This board is an advanced version of the board Arduino Mega 2560. However, when the nature of projects go complex that require more memory and a rich set of I/O interfaces, the Arduino Mega 2560 Rev3 comes into play. Other boards like Arduino Uno, Arduino Nano, Arduino Every, Arduino Beetle all seem a good pick for the projects that require little memory to store the program. Almost all boards work similarly with few exceptions.

The Arduino boards are widely used in the automation industry and embedded projects. The Arduino Mega 2560 Rev3 is a microcontroller board that is based on the ATmega2560 microcontroller. In this post today, I’ll walk you through the Introduction to Arduino Mega 2560 Rev3.
