Description
The Arduino Mega 2560
is a powerful microcontroller development board based on the ATmega2560
microcontroller. It is designed for applications requiring more I/O pins,
higher processing power, and expanded memory, making it ideal for complex
projects such as industrial automation, robotics, IoT systems, and large-scale
data processing.
The Mega 2560 features
54 digital I/O pins, 16 analog inputs, 4 hardware serial ports (UARTs), and a
large 256 KB flash memory, allowing developers to interface with multiple
sensors, displays, motors, and communication modules simultaneously.
It is widely used in
advanced embedded systems development, multi-device integration, and projects
requiring multiple serial communications or extensive memory usage.
