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. The Mega 2560 board can be programmed with the Arduino Software (IDE).

You can build your own board using the follwing files:ĮAGLE FILES IN. 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 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. The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet).
