MEGA2560 MEGA 2560 R3 (ATmega2560-16AU CH340G) AVR USB Board Development Board MEGA2560 PRO For Arduino Expansion Board

MEGA2560 R3 Development Board with ATmega2560-16AU and CH340G

Unleash the full potential of your Arduino projects with the MEGA2560 R3 development board. Built around the ATmega2560-16AU, this board delivers expansive I/O, robust processing, and reliable USB connectivity—perfect for complex projects that need more channels, more memory, and more control than a standard Arduino Uno.

Why this Mega stands out

• Powerful microcontroller: ATmega2560-16AU with 256 KB Flash (8 KB used by bootloader), 8 KB SRAM, and 4 KB EEPROM for large sketches and data logging.
• Extensive I/O: 54 digital input/output pins (14 capable of PWM) and 16 analog inputs for sensors, displays, motors, and peripherals in a single board.
• Quad UARTs: Four hardware serial ports for multitasking—ideal for robotics, data acquisition, and multi-device communication without running out of serial channels.
• CH340G USB-to-serial bridge: Reliable USB connectivity with widely available drivers for easy plug-and-play across Windows, macOS, and Linux.
• Arduino Mega R3 compatibility: Drop-in compatibility with shields designed for the Arduino Mega/R3 lineage, with enhanced pinout support for modern projects.
• Flexible power options: Operates at 5V with a recommended input range of 7–12V. Power via USB, a standard AC-to-DC adapter, or a battery for portable setups.
• Fully featured layout: 16 MHz crystal for precise timing, ICSP header for bootloader programming or in-system debugging, and a reset button for quick restarts during development.

Ideal use cases

• Robotics control systems requiring multiple sensors, motor drivers, and real-time decision making.
• Data logging projects gathering information from many analog and digital sources over extended periods.
• DIY CNC, 3D printer controllers, or automation projects that rely on simultaneous serial communication.
• Educational setups and prototype designs needing a feature-rich platform with shield compatibility.

What you get and how it helps you work smarter

• Ready-to-run hardware: A complete Mega 2560 R3 board compatible with a broad ecosystem of Arduino shields for rapid prototyping and scalable development.
• Driver readiness: CH340G driver compatibility streamlines setup across Windows, macOS, and Linux, reducing friction to get your first sketch running.
• Expandability and future-proofing: 54 I/O pins and generous flash space enable libraries for sensors, displays, and wireless modules without hitting early limits.
