This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the board show up as a keyboard, mouse, joystick, etc. In addition to all the features of the previous board, the Mega 2560 now uses an ATmega8U2 instead of the FTDI chip. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. Because it has bootloader, it can download programs directly from USB. It has 54 digital input/output pins, 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. DFRduino Mega1280 is a microcontroller board based on the ATmega1280. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It has 54 digital input/output pins (of which 14 can be used as PWM outputs). The Arduino Mega is a microcontroller board based on the ATmega2560. The MC-MEGA is a microcontroller board based on the ATmega1280 (datasheet). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). The Mega 2560 is based on AVR RISC Architecture. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. The Pinout of Arduino Mega is shown below: The description of pins present on the Arduino board are listed below: ATmega2560 Microcontroller - The Atmega2560 is a CMOS (Complementary Metal Oxide Semiconductor) low powered 8-bit microcontroller. This example makes use of one of Arduino Mega's 3 auxiliary serial. Sometimes, one serial port just isn't enough When trying to communicate with multiple serial enabled devices, while also sending info back to the main serial window, a few extra RX/TX ports can be a welcomed thing. This page is for reference only.Īrduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/ Wiring language. Use two of the serial ports available on the Arduino Mega. ![]() The new version has a few new pins and an ATMega16U2 instead of an 8U2. The Arduino Mega 2560 has been replaced by the Mega R3.
