Product Overview & Details
Arduino Mega 2560 R3
Take your electronics projects to the next level with the Arduino Mega 2560 R3 — the go-to board for makers who need more inputs, more outputs, and more processing power than a standard Arduino Uno can offer. With its extensive set of I/O pins and generous memory, the Mega 2560 is built for complex, large-scale projects like 3D printers, robotics, CNC machines, and multi-sensor automation systems.
Key Features:
- ATmega2560 microcontroller running at 16MHz
- 54 digital I/O pins (15 of which support PWM output)
- 16 analog input pins for sensor-heavy projects
- 256KB of flash memory (8KB used by bootloader), 8KB SRAM, and 4KB EEPROM
- 4 hardware UARTs for serial communication with multiple devices
- USB-B connection for programming and power
- DC power jack for external power supply (7-12V recommended)
- ICSP header for direct microcontroller programming
- Fully compatible with most Arduino Uno shields
Perfect For:
Makers, students, and engineers building projects that demand extra memory and I/O — think 3D printers, CNC controllers, robotic arms with multiple servos, home automation hubs, and complex sensor networks that outgrow the Uno's capabilities.
Whether you're prototyping an ambitious multi-component build or need the extra headroom for a growing project, the Arduino Mega 2560 R3 delivers the pins, power, and memory to bring it to life.
