![]() Red are differences, where the functionality has moved on Mega2560 compared to UNO. Green have the same function and position as the Arduino UNO R3. ![]() The Mega 2560 is an upgrade from theArduino Mega, which it replaces. Inspired by Nicks UNO pinout I did a similar one for the Arduino Mega2560 R3. The Mega 2560 board is compatible with most shields designed for the Uno and older Duemilanove or Diecimila boards. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with an AC-DC adapter or battery to get started. There are pin mappings to Atmega8 and Atmega 168/328 as well. Tech Specs Compatibility Suggested Libraries The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Below is the pin mapping for the Atmega2560. The board accommodates the ATmega2560 microcontroller, which operates at a frequency of 16 MHz. It has 54 digital input/output pins (15 of which can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power socket, an ICSP connector, and a reset button. A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. For more information on the Uno, check out this article.TheArduino Mega 2560 is a microcontroller board based on the ATmega2560. The Arduino Mega 2560 is a fantastic option for use in prototyping with ease, especially for 3D printers and robotics, where the Uno just doesn’t hold up. Arduino Comparison Chart: Boards & Modules. The Mega’s shield selection includes any shield compatible with the Arduino Duemilanove and Diecimila. Here you will find all of the technical documentation and support files for the Arduino Mega 2560 Revision 3. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection. Using a shield gives your Mega board display options, Wi-Fi connectivity or even video game emulation software with relative ease. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a. External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). These preassembled PCBs interface directly into the Mega’s headers and give the board incredible capabilities in a condensed package. The 8-bit board with 54 digital pins, 16 analog inputs, and 4 serial ports. With it, anyone can add to or use the massive selection of codes to provide easy access to a world of programming possibilities.Īnother prominent feature of all Arduino boards, including the Mega, are the Arduino shields. The open-source coding terminal has a variety of features that make it accessible to both novices and programming gurus alike, most notably the IDE’s associated library of projects and other syntaxes created by the massive community of Arduino users. Like the Uno, the Mega operates in the Arduino Integrated Development Environment (IDE). Arduino Mega 2560 Pinout DiagramĪs far as other hardware on the Mega goes, it also touts four serial ports for general attachments, a USB connection (with a dedicated ATmega16U2 processor for interfacing with your computer), a reset button and a power supply port. But the SDA and SCL are still on the other pins as well, because there is only one I2C bus. To allow a shield to connect with the I2C bus, those 2 pins near AREF are added. See the graphic below for a (dare I say) mega-map of the Mega’s pins. Yes, because the SDA and SCL are on different pin for the Arduino Uno, or the Leonardo or the Mega board. ![]() Because of its brawnier processor, the Mega has 54 digital I/O pins (15 of which can provide PWM output) and 16 analog pins, which is almost four times that of its little brother, the Uno. what should be the pin connection for that if anyone can help me. I am using adxl345 and Arduino mega 2560. The board contains 54 digital input/output pins, 16 analog inputs, 4 UARTs. The board accomodates the ATmega2560 microcontroller, which. compared to other maker boards by Arduino. Those pins are also available on the ICSP connector. Arduino® Mega 2560 is an exemplary development board dedicated for building extensive applications as. Thanks to the ATmega2560 (and its associated crystal oscillator), the Arduino Mega sports 16 MHz clocking speed, as well as 256 KB of flash, 8 KB of SRAM and 4 KB of EEPROM. Those pins are 52, 51, 50 and 53 (defalut) on a Mega. As stated before, the brain behind the Arduino Mega is the ATmega2560.
