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. This is not recommended because you bypass the LD1117S50CTR 5V voltage regulator and have to make sure that the voltage level is stable.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. You can also power power the Arduino microcontroller from the 5V pin. You cannot power the board with the barrel jack and VIN GPIO at the same time, because there is a polarity protection diode, connecting between the positive of the barrel jack to the VIN pin, rated at 1A. Therefore you are able to power the Uno with an external 9 Volt battery. The voltage has to be between 7V and 12V. VIN Pin: If you use an external power supply like a battery, you can use the VIN pin.If you buy a DC power jack, make sure the power adapter of the plug supplies a voltage between 7V and 12V. DC Power Jack: It is possible to use the DC power Jack as power supply.
The standard USB connection delivers 5V and allows you to draw 500mA in total.

There is no need for a voltage regulator because the USB connection is already regulated by the USB output from your PC or laptop. The Arduino Mega can also be powered via the USB port. The maximum output current of the LD1117S50CTR is 800mA. Besides a higher input voltage than 12V has no advantage. But an input voltage between 7V and 12V is recommended to use the Arduino Mega over an extended period of time because otherwise the voltage regulator produces a lot of heat that can damage the microcontroller. The LD1117S50CTR provides a stable 5V output for the ATmega2560 and has a maximum input voltage of 15V.
