This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply.ģV3. The regulated power supply used to power the microcontroller and other components on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.ĥV. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). 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. Revision 3 of the board has the following new features:ġ.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 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. If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 6 to 20 volts. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. 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. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.ĭigital I/O Pins 54 (of which 14 provide PWM output)įlash Memory 256 KB of which 8 KB used by bootloader 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.
