![]() Buying it, you're supporting the Arduino team (a part of the revenue is committed for further Arduino development). Thanks to this, Arduino can appear as different type of hardware (mass storage device, keyboard or another HID device) when connected to PC.Īrduino Mega 2560 boards sold by us are original. What's more, ATmega8U2 has its own firmware, which can be reprogrammed when necessary. What it means for the user? Additional 3.3V voltage regulator provides 150 mA of overall maximum output current (compare it to 50 mA offered by previous versions). This model is also equipped with a new USB module (so as Arduino UNO) based on ATmega8U2 chip (instead of FTDI chip used in previous models). The processor works with frequency of 16 MHz. Available memory is 256 KB of flash, 8 KB RAM and 4 KB EEPROM. Totally it has 54 digital inputs/outputs (including 14 capable of PWM operation), 16 analog inputs, 4 serial ports (UART), SPI and I2C interfaces. One could say, Arduino Mega is Arduino UNO's older brother - bigger memory, more input/output pins, so it's dedicated to more advanced applications than UNO. However, there are some differences between functions of particular pins, thus not every shield can be used with Arduino Mega. It means, the shields designed for Duemilanove will also fit to Mega board. The second one is a not connected pin, that is reserved for future purposes.įor more information, please see Arduino's details.NOTE! This is Arduino Mega 2560 version R2, we are offering also newer version - Arduino Mega 2560 R3.Īrduino Mega 2560 is a developer board based on ATmega2560 microcontroller.Īrduino Mega 2560 is compatible with Arduino Duemilanove/UNO footprint. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.Revision 3 of the board has the following new features: Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. ![]() Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 boards) programmed as a USB-to-serial converter. The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. The Mega 2560 is an update to the Arduino Mega, which it replaces. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. 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. 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, a power jack, an ICSP header, and a reset button. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. ![]()
