## Description

The Arduino Mega 2560 R3 is a microcontroller board based on the ATmega2560, offering significantly more I/O than standard Arduino boards. With 54 digital I/O pins, 16 analog inputs, and 4 hardware serial ports, it's the go-to board for complex projects that demand extensive connectivity. The R3 revision adds dedicated SDA and SCL pins next to the AREF pin, plus an IOREF pin that allows shields to automatically adapt to the board's voltage level. Compatible with most shields designed for the Arduino Duemilanove, Diecimila, and Uno. Key Features 54 Digital I/O Pins – 14 usable as PWM outputs 16 Analog Inputs – For extensive sensor arrays 4 Hardware UARTs – Multiple serial connections for GPS, Bluetooth, and other modules 256KB Flash Memory – Room for large, complex sketches R3 Pinout – SDA/SCL and IOREF pins for improved shield compatibility ATmega2560 – Powerful 8-bit microcontroller at 16MHz Specifications Microcontroller – ATmega2560 Operating Voltage – 5V Input Voltage – 7–12V Digital I/O Pins – 54 (14 PWM) Analog Input Pins – 16 Hardware Serial Ports – 4 UARTs Flash Memory – 256KB SRAM – 8KB EEPROM – 4KB Clock Speed – 16MHz Ideal For Projects requiring many I/O pins (LED arrays, multi-sensor setups) Robotics with multiple motors and sensors 3D printer controller boards Data logging with multiple serial devices Package Contents 1× Arduino Mega 2560 R3 Resources Schematic (PDF) Arduino IDE Download
