The Mega 2560 can be powered via the USB connection or with an external power supply. Flash Memory: 256 KB of which 8 KB used by bootloader.Digital I/O Pins: 54 (of which 15 provide PWM output).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 an 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. RX/TX LED – The RX and TX LEDs on the board will start flashing when data is being transmitted via USB-to-serial chip and USB connection to the computer.The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.You can use the Arduino ISP to upload sketches directly on the AVR-based Arduino boards without the need of the bootloader ICSP Header Pins contains six pins MISO(Master In Slave Out), +Vcc, SCK(Serial Clock), MOSI(Master Out Slave In), Reset, GND. It is used to program AVR microcontrollers. ICSP Header Pins – a Full form of ICSP is In-Circuit Serial Programming also called In-System Programming (ISP).When Master Reset Button is pressed, it sends the logical pulse to the reset pin of the micro-controller. It is useful when the programmer wants to run the program from the starting point. Master Reset Button – Master Reset Button is used to reset the Arduino MEGA board and restart the running program from starting.If the power voltage of the power port is more than 12V, the voltage regulator may overheat and damage the board. It also regulates the voltage for 5V and 3V3 pins. Voltage Regulator – The main work of the Voltage Regulator is to regulate the input and output voltage of the Arduino MEGA board. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs to work with the 5V or 3.3V.
