Arduino Mega has inbuilt reset circuit with push button to reset system and this pin can be used by other devices to reset controller.For comparison, heres the official photograph from top above again from the Arduino store: Lets model them in Systems Modeling Language (SysML) using the. Technical Specifications of Arduino Mega01/01 Arduino Uno R3 Pinout Diagram Pdf Written By phoem Thursday, January 1, Add Comment Edit Arduino Pinout Diagrams Marcusjenkins Com Arduino Uno.Arduino Mega Pin Diagram Arduino Mega Pin Configuration Controller Pins: RESET: (Reset input) A low level on this pin for longer than the 4 clock cycle will generate a reset. This input has no connection to the five volt USB connector or other stabilization voltage. Powering PINs: VIN supplying voltage from an external power supply. Before connecting, it is important to present the Arduino Leonardo’s pinout and understand the intricacies of connection.

Apart from that, the layout of Arduino Mega is very much self-explanatory.I will discuss about the pins of Arduino Mega in the Arduino Mega Pinout Section. There is also a 2.1 mm DC jack to provide external power supply. Layout of Arduino Mega BoardAs 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. Arduino Mega Board LayoutThe following image shows the layout of a typical Arduino Mega board. It is available in a 100-pin Quad Flat Package.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.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.

8 KB of the Flash Memory is used by the bootloader code.What are the Input and Output Pins of Arduino Mega?Of the 86 pins available on the Mega board, 72 pins are associated with input and output. There are three different memories available in ATmega2560. What are Different Memories of Arduino Mega?Strictly speaking, this is specific to the MCU i.e., ATmega2560, used on the Arduino Mega Board. The next way is to provide an unregulated supply in the range of 6V to 20V to VIN pin of the 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 first and easy way is using the Type-B USB Connector. But none the less, let me give you a brief overview about some important technical specifications of Arduino Mega 2560.There are a couple of ways in which you can power the Mega board.

They are:Perhaps the most common communication interface in the Arduino universe is the Serial Communication. Communication Interfaces on Arduino MegaArduino 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.An important point about Analog Input pins is that they can be configured as Digital IO pins, if required.Digital IO pins 2 – 13 and 44 – 46 are capable of producing 8-bit PWM Signals. The value of the internal pull-up resistor will be in the range of 20KΩ to 50KΩ.There are also 16 Analog Input Pins (A0 to A15). An additional feature of the Digital IO pins is the availability of internal pull-up resistor (which is not connected by default).

But ICSP doesn’t need any bootloader. But using the AREF pin, you can manually set the upper limit of the ADC.Using the IOREF pin, you can set the reference voltage for Microcontroller operations.To reset the microcontroller, you can use the on-board RESET button.Although you can program the Arduino Mega using the USB cable, there is a provision to program the MCU using the In-Circuit Serial Programming (ICSP) interface.The UART bootloader, which is preloaded in to the ATmega2560 Microcontroller, enables programming through serial interface. The reference voltage for the internal ADC is by default set to 5V. Use this LED to perform Blinky operations.

ConclusionThis was a brief overview on Arduino Mega board layout, technical specifications, important features and most importantly the complete Arduino Mega Pinout information. Arduino Mega PinoutAs you can see from the image, I described each pin of the Arduino Mega with its Microcontroller equivalent pin, alternative functions, default functionality and other additional features.For higher resolution image, click here. The following image shows the complete pinout of Arduino Mega Board. Arduino Mega PinoutNow that we have seen a little bit about Arduino Mega and its important features and specifications, let us dive into the Arduino Mega Pinout. Use attachInterrupt() function to configure the Interrupt for rising edge, falling edge or level change on the pin.If you want use any Shields, then Arduino Mega is perfectly compatible with most of shields designed for Arduino UNO.
