The Arduino Mega 2560 Rev3 is a powerful 8-bit microcontroller board based on the ATmega2560, designed for users who need more I/O pins, memory, and functionality than the standard Arduino Uno. It is ideal for advanced projects that require multiple sensors, motors, displays, and complex control systems.
With a whopping 54 digital I/O pins (15 of which support PWM), 16 analog inputs, and 4 hardware serial ports (UARTs), the Mega 2560 provides the resources needed for serious makers, engineers, and educators building sophisticated electronics and automation systems.
ATmega2560 Microcontroller
Delivers robust performance at 16 MHz, ideal for multitasking and handling resource-heavy applications.
54 Digital I/O Pins & 16 Analog Inputs
Accommodates a wide range of sensors, actuators, and other components—perfect for large-scale embedded systems.
4 UARTs (Serial Ports)
Enables multiple serial communications simultaneously—great for GPS, Bluetooth, and serial sensors.
High Memory Capacity
Comes with 256 KB Flash memory, 8 KB SRAM, and 4 KB EEPROM—ample space for complex sketches and data handling.
Universal Compatibility
Supports most shields made for Arduino Uno and older boards like Duemilanove or Diecimila.
Plug-and-Play
Easily powered via USB or an external adapter (7–12V recommended), making it beginner-friendly yet scalable for professionals.
