Power Supply
Mega2560 can be connected by USB or powered by external power supply to automatically select power supply.Automatic power selection. The external (non USB) power supply can be AC-DC adapter (wall type); The battery can also be connected to the adapter by inserting the 2.1 mm central positive plug into the power socket of the circuit board. The lead of the battery can be inserted into the GND and VIN pins of the power connector. The recommended voltage range is 7-12V.

Input and output
Using pinmode, digitalwrite and dighi talread  functions, 54 digital pins on mega can be used as input or output, and their working pressure is 5V. Each pin can supply or receive 40 ma current.

Each has a 20-50k internal pull-up resistor (disconnected by default).

USB over current protection
Mega 2560 has a self recovery fuse, which can protect the computer USB port from short circuit and over-current damage. If the current on the USB interface exceeds 500 mA, the fuse will automatically cut off the connection until the short circuit or over-current condition.

Physical characteristics
Four screw holes allow the board to adhere to the surface.

What’s the difference with other development boards?
Mega2560 is different from all previous circuit boards because it does not use ftdi USB to serial driver chip. Instead, atmegal6u2 (atmege8u2 in R1 and R2 boards) is programmed into a USB to serial converter.

The mega2560 board R2 has a resistor to ground the 8u2hwb line, making it easier to enter DFU mode.

Mega2560 has 16 analog inputs, each of which provides 10 bit allocation rate (i.e. 1024 different values). By default, their voltage is 0- 5V, although the upper limit of their range can be changed by using aref pin and analogreference0 function.

There are two more pins on the circuit board
AREF   The reference voltage of the analog input is used with the analog reference.
Reset   Lower the line value to reset the microcontroller, which is usually used to add a reset button to the shield board.

Mega 2560 is a microcontroller board based on the ATmega2560. 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. 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. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.

The Mega 2560 is an update to the for Arduino Mega, which it replaces.You can find here your board warranty informations.

Getting Started
You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics.

Pro Mini MEGA2560

Embed version of Mega 2560 CH340G/ATmega2560 – compatible with Arduino Mega 2560 board. Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G.

Board have compact size 38x55mm. It is good solution, to make your final project on solder proto- board.

Board for functionality similar to the Arduino Mega 2560. It is embed board, but the same stable, and uses the original chips ATmega2560 (16 MHz).

The board used the chip CH340G as converter UART-USB. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer).
Mega PRO (Embed) 2560 CH340G / ATmega2560 – connects to the computer via microUSB cable (used for almost all Android smartphones). .

You can supply power to board through the MicroUSB connector or to power pinheaders. The voltage regulator (LDO) can deal with incoming voltage from 6V to 9V (peack 18V) DC. Output current for 5V – about 800mA, for 3.3V – about 800mA(Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.
