Resettable Polyfuse : ( to provide extra layer of protection.Indeed a remarkable addition in Arduino MEGA 2560 ) ICSP header ( Used to program the board and to upload code from computer.USB cable port ( It is used to transfer and connect code from computer the board ).Crystal oscillator is added on the board having frequency of 16 MHz.USART pins : 4 ( These are hardware serial ports which produces maximum speed to set up communication ).15 pins out of this are useful for PWM ( pulse width modulation ).In digital side 54 pins for I/O ( input output pins ).Mostly it is used for creating a stand-alone project It can be used as a stand-alone project or in combination with other boards. It is designed for more complex projects because as for simple projects large amount of input output pins are useless and a board with less memory fails to achieve our requirements. As per our requirements we can just plug and play with this board as everything is built in that makes it readily available.Īrduino Mega 2560 is an amazing microcontroller board for the projects that need large amount of input output pins or if high processing power is required. We don’t need to attach extra components or devices to make this board in running condition to use. It is programmed in Arduino IDE software like all other boards in terms of coding. Instead it uses ATmega16U2 programmed as a USB-to-serial converter. Arduino MEGA 2560 is different from all other boards of Arduino that came before as they don’t use the FTDI USB-to-serial driver chip. It can have more memory space as compared to other boards of Arduino. This board is the successor of Arduino MEGA. It is way more powerful than Arduino UNO and also twice as long from it. INTRODUCTION TO Arduino mega 2560Īrduino MEGA 2560 board is just like a brother of Arduino UNO board. We will also highlight some application and projects that are made from this board and much more. You will also get to know about the specifications of this board, pins configuration, components, software that is used to program this board, memory, power requirements and additional shields that can be used with board. After reading this article you will get to know that how this board is different from other boards of Arduino, in which condition or under which specifications we should use this board and why we should prefer this board over others. Actually ATmega2560 is SMD component and costs over 50% of China Clones of Mega making it buying China Clone practical for first time.In this article we are going to discuss briefly about Arduino Mega 2560 board. Many of these are clones, are quite good and reliable, and some have desirable features not found on official boards!Ĭan we build Arduino Mega on Breadboard like Arduino UNO? Yes, but only for special need for hardware tweak. There are Mega clones which bring out every pin to a header. Ordinary projects for 1-2 sensors, LEDs will have no difference.īuying Arduino Mega demands some idea around electronics. In reality, Arduino Mega is for the Advanced users for certain projects. When we are using I2C, we will will not be able to use pins A4 and A5 as they are being dedicated to the communication. Two of the analog pins of Arduino Mega are also usable for the I2C interface. But all codes for Arduino UNO will work on Arduino Mega. Not all codes for Arduino Mega actually will work on Arduino UNO. If your project has specific serial communication matters, Arduino Mega is practical. If your project is around robotics with multiple motors and other sensors, Arduino Mega is practical. Of course, CPU speed and RAM is more for Arduino Mega. The shields which are compatible with Arduino Uno are also compatible with Arduino Mega but difference is that, you’ll have lot of pins still available on Arduino Mega. On UNO there will be one RX pin and one TX pins, in addition Arduino Mega has 3 Rx pins and 3 TX, 1 SDA pin and 1 SCL pins. 15 can be used as PWM outputs, 16 analog inputs, 4 UARTs. So we can avoid the method described earlier to increase the port number. Arduino Mega provides plenty of pins, plenty in the sense way to much more than Arduino Uno. 6 of them (D3, D5, D6, D9, D10, and D11) can be used as PWM outputs and 6 analog inputs, one serial communication line (D0, D1). Arduino Uno is a microcontroller board based on the ATmega328 which has 14 digital input/output pins.
