Arduino Mega 2560 R3

Arduino Mega 2560 R3

Product Overview

The Arduino Mega 2560 R3 from Pro Tronix is the ultimate upgrade for makers who have outgrown the limitations of the Arduino Uno. Powered by the ATmega2560 microcontroller, this board provides significantly more “room to grow” with four times the flash memory and eight times the SRAM of the Uno.

Its standout feature is the massive array of 54 digital I/O pins, allowing you to control dozens of LEDs, sensors, and actuators simultaneously without needing multiplexers. It also features 4 hardware serial ports (UARTs), which is a lifesaver for projects requiring simultaneous communication with multiple devices like GPS modules, Bluetooth, and Nextion displays. The R3 version also adds dedicated SDA and SCL pins for easier I2C communication.

Technical Specifications

Key Features

• Massive Expansion: 54 digital pins and 16 analog pins make it perfect for sensor-heavy applications.

• Complex Sketch Support: 256KB of flash memory allows for very large and complex programs that wouldn’t fit on smaller boards.

• Multi-Serial Support: 4 hardware UARTs allow for high-speed, reliable communication with multiple peripherals at once.

• Shield Compatibility: While much larger, it is still compatible with most shields designed for the Arduino Uno, Duemilanove, or Diecimila.

• Reliable Power: Features an improved power circuit and a stronger reset circuit compared to previous iterations.

Common Applications

• 3D Printers: The core of the RAMPS 1.4/1.6 setup used in countless DIY 3D printer builds.

• Robotics: Controlling multi-axis robotic arms or hexapods that require many PWM signals and sensor inputs.

• CNC Machines: Driving multiple stepper motors and limit switches for laser cutters and routers.

• Home Automation Hubs: Managing complex smart home systems with dozens of wired sensors and relays.
