The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. 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. It has 54 digital input/output pins (of which 14 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. The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet).

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? PWM Pins:ĭigital pin 2-13 can be used as PWM output with analogWrite() to write pwm value from 0-255.It’s alternative of DAC for low cost system to get analog signal at output by using filter. It can be used by pinMode() for pin direction, analogRead() to read pin status and get digital value for analog signal, care must be taken for internal or external reference voltage selection and Aref pin. Analog Pins (16):Īnalog pins: From 0-15(analog) can be used as analog input pin for adc, if not used than it work as normal digital pin. Revision 3 of the Mega ADK board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU(Device Firmware Upgrade) mode.ĭigital pins (70): Digital pins (0-53) + Analog (0-15) = Total Digital I/O pins.ĭigital Pins: From 0-53(digital) and 0-15(analog) can be use as input or output for digital transducer and output devices by pinMode() for pin direction, digtalWrite() to write pin and digitalRead() to read pin status. Similar to the Mega 2560 and Uno, it features an ATmega8U2 program as a USB-to-serial converter. It has a USB host interface to connect with Android based phones, base on the MAX3421e IC.ĪTmega2560P 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. Atmega 2560P based Arduino Mega pinout and specifications are given in detail in the below.The ATmel MCU ATMEGA16U2 MEGA 2560 R3 Improved Version CH340G Board is a micro-controller board base on the ATmega2560. The Atmega3560P is an 8-bit microcontroller that comes with a built-in bootloader, which makes it very convenient to flash the board with our code. It is based on the Microchip ATmega2560P by Atmel. The Arduino Mega is an open-source development board that is developed by the Arduino company.
