![]() Most of the computers come with an ability to protect themselves from such devices, however, the addition of fuse provides an extra layer of protection. This board comes with resettable polyfuse that prevents the USB port of your computer from overheating in the presence of high current flowing through the board.Last two sources to power the board are required once you already built and compile code into the board through USB cable.You can either use a USB cable to power the board and transfer code to the board or you can power it up using Vin of the board or through Power jack or batter. There are three ways to power the board.However, there are some projects that are solely done by Arduino Mega like making of 3D printers or controlling more than one motors, because of its ability to store more instructions in the code memory and a number of I/O digital and analog pins. Most of the electronic projects can be done pretty well by other boards available in the market which make Arduino Mega uncommon for regular projects. Arduino Mega is specially designed for the projects requiring complex circuitry and more memory space.The following figure shows the specifications of Arduino mega 2560.There is a reset button and 4 hardware serial port called USART which produces a maximum speed for setting up communication.Availability of Atmega16 on the board makes it different than Arduino Pro Mini which uses USB to serial converter to program the board.Arduino software called Arduino IDE is used to program the board which is a common software used for all boards belonged to Arduino family.There is no much difference between Arduino Uno and Arduino Mega except later comes with more memory space, bigger size and more I/O pins.5V and 3.3V which provides the flexibility to regulate the voltage as per requirements as compared to Arduino Pro Mini which comes with only one voltage regulator. This board comes with two voltage regulator i.e. ![]()
