The Mega is compatible with most shields designed for the Arduino Uno, 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. The following boards use the same ATmega2560 processor and have more or less similar pinout and functionality: The Arduino Mega 2560 Rev3 - This board is an upgrade to the original Arduino Mega and features the same ATmega2560 microcontroller as the Arduino Mega ADK. So far as I see there is no way to write 7 or 8 bits to a single port as a digital output on any port on the 328P. A6 and A7 do not work as digital outputs with the 328P. ![]() 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. this picture from the official Arduino site showed a total of 69 digital pins: ' The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. I used a Nano classic because it exposed A0-A7, of which I used A0-A6 to write 7 bits to the port simultaneously. The Arduino digital pins can read only two states: when there is a voltage signal and when there is no signal. Board Arduino Mega 2560 adalah sebuah Board Arduino yang menggunakan ic Mikrokontroler ATmega 2560.Board ini memiliki Pin I/O yang relatif banyak, 54 digital Input / Output,15 buah di antaranya dapat di gunakan sebagai output PWM, 16 buah analog Input, 4 UART. All the Pins between 0 to 53 are digital input/output pins. ARDUINO MEGA 2560 MIKROKONTROLER ATmega2560. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Arduino Mega 2560 has 54 digital I/O pins. Das Design des Mega ist gut überdacht, denn die Anordnung der I/O PINs sind so angeordnet das Shields welche für den Arduino UNO entwickelt wurden einfach auf den Mega gesteckt werden kann. Einzig das der Mega deutlich mehr analoge und digitale PINs besitzt. ![]() Description: Arduino Mega 2560 R3 Interface Circuit I/O Card Der Arduino Mega 2560 R3 hat sehr viel mit dem Arduino UNO gemeinsam.
