Arduino Mega 2560 R3 Rev3 Atmega 2560-16AU CH340G Circuit Board (Original New Version) + Cable

Arduino Mega 2560 R3 is a microcontroller board based on ATmega2560 microcontroller.

It is an upgraded version of the original Arduino Mega board and offers more input/output (I/O) pins, more memory, and more features compared to other Arduino boards.

Some key features of Arduino Mega 2560 R3 are:

Microcontroller: Uses the ATmega2560 microcontroller, an 8-bit AVR microcontroller with 256KB flash memory, 8KB SRAM, and 4KB EEPROM.

Digital I/O Pins: The Mega 2560 has a total of 54 digital input/output pins, 15 of which can be used as PWM (Pulse Width Modulation) outputs.

Analog Inputs: It has 16 analog input pins that can be used to read analog signals from sensors or other analog devices.

Communication Interfaces: Multiple on-board features, including 4 hardware UART (Universal Asynchronous Receiver/Transmitter) serial ports, a USB connection for serial communications and programming, an SPI (Serial Peripheral Interface) port, and an I2C (Integrated Circuit) communication interface is located ) port.

Operating Voltage: The Mega 2560 operates at 5V and can be powered using a USB connection or an external power supply.

Memory: The ATmega2560 microcontroller on the Mega 2560 has 256 KB flash memory used to store the Arduino sketch (program), 8 KB SRAM for storing variables and runtime data, and 4 KB EEPROM for non-volatile storage.

Compatibility: Mega 2560 is compatible with Arduino software (IDE) and can be programmed using the C/C++ based Arduino programming language.

It also supports Arduino libraries and a wide variety of shields and modules.

Arduino Mega 2560 R3 is commonly used in projects requiring large numbers of I/O pins, such as robotics, automation, 3D printers, and complex sensor systems.

Its expanded capabilities make it a popular choice for more advanced and demanding applications.
