Specifications

Why Choose the Original Arduino Mega 2560 Rev3?

• 100% Authentic Arduino: Genuine board made in Italy - not a clone. Verified from authorized distributors with full Arduino ecosystem support and guaranteed quality.
• Massive I/O Capacity: With 54 digital pins, 16 analog inputs, and 4 hardware serial ports, it handles complex multi-sensor, multi-actuator projects that smaller boards simply cannot.
• 256 KB Flash Memory: Run large, sophisticated sketches with extensive libraries - 4x the memory of the Arduino Uno.
• 4 Hardware Serial Ports: Communicate simultaneously with GPS modules, Bluetooth, GSM shields, and serial displays without software serial conflicts.
• Full Shield Compatibility: Pin-compatible with thousands of Arduino shields, including motor shields, Ethernet shields, TFT displays, and sensor shields.
• ATmega16U2 USB Chip: Rev3 uses a dedicated ATmega16U2 for USB-to-serial conversion, providing faster, more reliable communication than CH340/CP2102 clones.
• The Engineer Store Power Management: Automatic power source selection between USB and external supply, with built-in voltage regulation and overcurrent protection via resettable polyfuse.
• 1-5 days shipping: Ships from our Bengaluru warehouse to most Indian cities. Same-day delivery available within Bengaluru.
• Expert Technical Support: Get help with wiring, code, and project design from our engineering team - included free with every purchase.

Key Features in Detail

• ATmega2560 Processor: 8-bit AVR RISC architecture running at 16 MHz, delivering reliable real-time performance for sensor reading, motor control, and data processing.
• 15 PWM Outputs: Precise analog-style control for servos, LED dimming, motor speed regulation, and audio generation across 15 dedicated pins.
• 6 External Interrupts: Respond instantly to hardware events on pins 2, 3, 18, 19, 20, and 21 - essential for encoders, limit switches, and real-time triggers.
• Built-in LED: Onboard LED connected to pin 13 for quick testing and debugging without external components.
• ICSP Header: In-Circuit Serial Programming header allows direct AVR programming and firmware updates via external programmers.
• Reset Button: Conveniently placed reset button for quick program restarts during development and testing.
• 3.3V and 5V Output: Onboard regulated power outputs to power external sensors, modules, and shields directly from the board.
