This pin outputs a regulated 5V from the regulator on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. The input voltage to the board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). 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 become 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 Mega 2560 can be powered via the USB connection or with an external power supply. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. The Mega 2560 has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. See this user-contributed tutorial for more information. Or you can use the ISP header with an external programmer (overwriting the DFU bootloader). You can then use Atmel's FLIP software (Windows) or the DFU programmer (Mac OS X and Linux) to load a new firmware.

On Rev2 or later boards: there is a resistor that pulling the 8U2/16U2 HWB line to ground, making it easier to put into DFU mode.

On Rev1 boards: connecting the solder jumper on the back of the board (near the map of Italy) and then resetting the 8U2.

The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by:

The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository.

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar see these instructions for details. It communicates using the original STK500 protocol ( reference, C header files). The ATmega2560 on the Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. For details, see the reference and tutorials.

Arduino mega 2560 pinouts update#

The Mega 2560 is an update to the Arduino Mega, which it replaces. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards 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.
