#ARDUINO MEGA 2560 PINOUTS SERIAL#

These pins are connected to the serial pins of the on-board USB to Serial Converter IC. Digital IO pins 0 and 1 are used as Serial RX0 and TX0 pins to receive and transmit serial data. In fact, the Arduino boards (UNO or Nano or Mega) are programmed using the serial communication.Īrduino Mega supports four hardware Serial Communication interfaces. Perhaps the most common communication interface in the Arduino universe is the Serial Communication. Communication Interfaces on Arduino MegaĪrduino Mega supports three different types of communication interfaces. You can use analogWrite() function for this. All the analog input pins provide a 10-bit resolution ADC feature, which can be read using analogRead() function.Īn important point about Analog Input pins is that they can be configured as Digital IO pins, if required.ĭigital IO pins 2 – 13 and 44 – 46 are capable of producing 8-bit PWM Signals. There are also 16 Analog Input Pins (A0 to A15). The value of the internal pull-up resistor will be in the range of 20KΩ to 50KΩ. An additional feature of the Digital IO pins is the availability of internal pull-up resistor (which is not connected by default). In that 54 pins (D0 to D53) are true digital IO pins, which can be configured as per you application using pinMode(), digitalWrite() and digitalRead() functions.Īll these Digital IO pins are capable of sourcing or sinking 20mA of current (maximum 40mA is allowed). Of the 86 pins available on the Mega board, 72 pins are associated with input and output. What are the Input and Output Pins of Arduino Mega?

8 KB of the Flash Memory is used by the bootloader code.

There are three different memories available in ATmega2560. Strictly speaking, this is specific to the MCU i.e., ATmega2560, used on the Arduino Mega Board.

What are Different Memories of Arduino Mega? You can also supply the unregulated supply through the 2.1mm DC Jack, in which case, you can access the supplied voltage through the VIN Pin. The next way is to provide an unregulated supply in the range of 6V to 20V to VIN pin of the Mega. The first and easy way is using the Type-B USB Connector. There are a couple of ways in which you can power the Mega board. But none the less, let me give you a brief overview about some important technical specifications of Arduino Mega 2560. Technical Specifications of Arduino MegaĪs Arduino Mega is based on ATmega2560 Microcontroller, the technical specifications of Arduino Mega are mostly related to the ATmega2560 MCU. I will discuss about the pins of Arduino Mega in the Arduino Mega Pinout Section. Apart from that, the layout of Arduino Mega is very much self-explanatory. There is also a 2.1 mm DC jack to provide external power supply. Layout of Arduino Mega BoardĪs you can notice, there is a Type-B USB connector on the left short edge of the board, which is used for powering on the board as well as programming the Microcontroller. Unlike Arduino Nano, all the components are placed on the top side of the PCB. The following image shows the layout of a typical Arduino Mega board. So, if you are developing some advanced robotic projects or 3D Printing hardware and want to use the Arduino environment, then Arduino Mega 2560 is the board for you. It is designed and developed to provide more number of IO lines (both Digital and Analog), more flash memory and more RAM when compared to UNO. It is available in a 100-pin Quad Flat Package. It can be considered as a big brother to both UNO and Nano, both in terms of size as well as features.Īrduino Mega is based on ATmega2560 Microcontroller, an 8-bit AVR Architecture based MCU from ATMEL. While Arduino Nano is a breadboard friendly version of Arduino UNO with more or less the same features, Arduino Mega is completely a different board. The answer to this is the Arduino Mega Board. Since the introduction of Arduino UNO as a quick prototyping board, there has always been a demand for more features than what Arduino UNO can offer. Communication Interfaces on Arduino Mega.
