This pin is used for serial usart communication with pc or other system for data sharing and logging.
Programming AVR controller, communication with others peripheral like LCD and SD card with four-line communication at high speed. SPI enable bit must be set to start communication with other devices. These pins are used for serial communication with SPI protocol for communication between 2 or more devices.
USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USARTĪrduino Mega – Advanced Features Arduino MegaĪrduino Mega 2560 is also packed with additional features like Analog Comparator, External Interrupt & Software Interrupt, Power Saving Mode, Inbuilt Temperature Sensor, RTC and more. Arduino Mega 2560 SpecificationsĪrduino Mega – Basic Features Arduino Mega Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones like Radon detectors, 3D printers, temperature sensing, IOT applications, real-time data monitoring applications etc. The Arduino Mega 2560 is a replacement of the old Arduino Mega, and so in general reference, it will be called without the ‘2560’ extension. It supports ICSP as well as USB microcontroller programming with PC. It is also compatible with the different type of boards like high-level signal (5V) or low-level signal (3.3V) with I/O ref pin.īrownout and watchdog help to make the system more reliable and robust.
With large FLASH memory and SRAM, this board can handle large system program with ease. Other features include JTAG support for programming, debugging and troubleshooting. It has more than 5 pins for Vcc and Gnd to connect other devices to Arduino Mega. Secondly, it has inbuilt RTC and other features like analog comparator, advanced timer, interrupt for controller wakeup mechanism to save more power and fast speed with 16 Mhz crystal clock to get 16 MIBS. First feature is the large I/O system design with inbuilt 16 analog transducers and 54 digital transducers that supports with USART and other communication modes. When cheaper boards are available, why go with Arduino Mega? The main reason behind this is the additional features that are inbuilt with this board.
