The Arduino Mega 2560 is a complete microcontroller development board of ATmega2560. Arduino Mega has a greater number of Input-output pins and gives larger space for the project making so, it is useful for more complex projects. The Arduino Mega is a kind of plug and plays the system like you just need to connect a cable with a phone or laptop and you are ready to work with.

Arduino Mega board everything that is needed for any DIYers and makers.

Onboard Components

• It has 54 digital input-output pins in which 14 pins provide PWM output and 16 Analog output pins
• 4 UARTs
• A crystal oscillator of 16MHz
• To Power, it has a USB connection and a Power jack
• ICSP header
• And, a reset button to reload or load a new program

Specification

• Microcontroller used: ATmega2560
• Logic level Operating Voltage: 5V
• Recommended Input Voltage: 7-12 V
• Limited Input Voltage: 6-20 V
• Pins for Digital Inputs Outputs: 54 of which 14 pins provide PWM output
• Pin for Analog Inputs: 16
• DC Current for each input-output pins: 40 mA
• Flash Memory: 256 KB in which bootloader uses 8 KB
• SRAM and EEPROM: 8 KB and 4 KB Respectively
• Clock Speed of board: 16 MHz as has 16MHz Crystal Oscillator

Instruction

• Make sure to insulate the base when the board is powered
• If the board is getting a heat, disconnect from the laptop or other power sources

Programming instructions

• The most common way to program Arduino Mega is Arduino IDE software
• The microcontroller in Arduino Mega, Atmega2560 comes pre-burned with bootloader because anyone can burn or upload a new code without any external hardware programmer and communicates using the original STK500 protocol.
