The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery.

The Arduino Mega can be powered via the USB connection or with an external power supply. Pin Mapping: PinMap2560 page Summary Microcontroller Schematic: arduino-mega2560_R3-schematic.pdf Schematic, Reference Design & Pin MappingĮAGLE files: arduino-mega2560_R3-reference-design.zip The second one is a not connected pin, that is reserved for future purposes. 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 ( datasheet).
