Arduino MEGA 2560 Rev3
The Arduino Mega 2560 Rev3 is a powerful microcontroller board based on the ATmega2560. Designed for projects requiring extensive input/output (I/O) capabilities, more sketch memory, and increased RAM, it surpasses the capabilities of smaller boards like the Arduino Uno. Featuring 54 digital I/O pins, 16 analog inputs, and a robust memory capacity, the Mega 2560 is perfect for complex applications such as robotics, data logging, and home automation. This open-source hardware platform is ideal for hobbyists, makers, and professionals looking to build sophisticated electronic projects.
FEATURES :
- Microcontroller: ATmega2560
- 54 Digital I/O Pins: Includes 15 pins with PWM (Pulse Width Modulation) output capability
- 16 Analog Input Pins: For precise sensor readings
- 4 Hardware Serial Ports (UARTs): Enables communication with multiple devices simultaneously
- Clock Speed: 16 MHz for efficient processing
- USB Connection: For programming and power supply (Type-B connector)
- ICSP Header: Supports in-circuit serial programming
- Power Jack: Accepts external power via an AC-to-DC adapter or battery
- Reset Button: Allows quick restarts of the board
- Large Memory:
- 256 KB Flash Memory (8 KB used by bootloader)
- 8 KB SRAM
- 4 KB EEPROM
- Shield Compatibility: Works with most Arduino Uno shields, enhancing functionality
- ATmega16U2 USB-Serial Processor: Improves interfacing flexibility
- Operating Voltage: 5V for reliable performance
Because this board uses the original Atmega16U2 for the USB converter, it does not require a different driver as the CH340 version does. It costs a little more, but it provides the maximum level of compatibility with the original Arduino Mega 2560 R3 and will identify as Arduino/Genuino Mega 2560 in the IDE.
The Mega 2560 operates at 5V which can be supplied via an external power supply or through the USB port connection. The power source is selected automatically if both are available. If an external supply is used, it is recommended to use a supply between 7-12V. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat.
The attached Mega 2560 board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Refer the the Arduino documentation for all possible functions for the pins.
