## Description

The Arduino Mega 2560 Rev3 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 Rev3 update introduces the ATmega16U2 USB-to-serial converter (replacing the 8U2), the 1.0 pinout with dedicated SDA/SCL pins and IOREF for improved shield compatibility, and a stronger reset circuit. Compatible with most shields designed for the Arduino Uno, Duemilanove, and Diecimila. 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 (8KB used by bootloader) Rev3 Pinout – SDA/SCL and IOREF pins, ATmega16U2 USB-to-serial converter Broad Shield Compatibility – Works with most existing Arduino shields Specifications Microcontroller – ATmega2560 Operating Voltage – 5V Input Voltage – 7–12V recommended (6–20V limits) Digital I/O Pins – 54 (14 PWM) Analog Input Pins – 16 Hardware Serial Ports – 4 UARTs DC Current per I/O Pin – 40mA DC Current for 3.3V Pin – 50mA Flash Memory – 256KB (8KB used by bootloader) 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 Rev3 Resources Schematic (PDF) ATmega2560 Datasheet (PDF) Arduino IDE Download Arduino Getting Started Guide
