4/23/2024 0 Comments Arduino mega 2560 pin 'A'![]() ![]() Flash Memory like 256 KB where 8 KB of flash memory is used with the help of bootloader.DC Current for each input/output pin is 40 mA.The digital input/output pins are 54 where 15 of these pins will supply PWM o/p.The input voltage will range from 6volts to 20volts.The recommended Input Voltage will range from 7volts to 12volts.The operating voltage of this microcontroller is 5volts.The specifications of Arduino Mega include the following. These boards work with every existing shield although can adjust to latest shields which utilize these extra pins. Another pin is not associated & it is kept for upcoming purposes. One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Additionally, there are two latest pins located near the RST pin. The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. This board can be protected from the unexpected electrical discharge by placing a base plate. So, the power supply of this board can be done by connecting it to a PC using a USB cable, or battery or an AC-DC adapter. This board mainly includes everything which is essential for supporting the microcontroller. It includes digital input/output pins-54, where 16 pins are analog inputs, 14 are used like PWM outputs hardware serial ports ( UARTs) – 4, a crystal oscillator-16 MHz, an ICSP header, a power jack, a USB connection, as well as an RST button. ![]() XTAL1,XTAL2: The crystal oscillator (16Mhz) is connected to the controller clock and is grounded through 2 bypass capacitors.ĪREF: Using this pin, when we use ADC for analog-to-digital conversion, use external reference voltage for conversion instead of reference voltage from internal 1.1V or 5v reference.The microcontroller board like “Arduino Mega” depends on the ATmega2560 microcontroller. The Arduino Mega has a built-in reset circuit, a key reset system, and can be used as a reset controller for other devices. RESET: (Reset input) The low level of this pin exceeds 4 clock cycles and the board will reset. ![]() The Arduino Mega 2560 also adds features such as analog comparators, external and software interrupts, power save mode, built-in temperature sensor, RTC, and more. USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USART Arduino Mega 2560 Hardware Specifications Arduino Mega 2560 So for some more complex projects, this is an excellent choice. The Arduino Mega 2560 is a replacement for the older model Arduino Mega, so, it will be named the "2560" extension. Other features of the Arduino Mega 2560 include JTAG support for programming, debugging and troubleshooting large flash and SRAM that can easily handle bulky programs it is also compatible with different types of modules such as high-level (5V) or low-voltage Flat (3.3V) and I/O ref pins it supports ICSP and USB microcontroller programming on the PC side. There are more than 5 sets of Vcc and Gnd pins, which can easily connect other devices to the Arduino Mega 2560. Built-in RTC and other functions, such as analog comparator, advanced timer, controller wake-up mechanism interrupt, etc., 16MHz crystal clock can get 16 MIBS, and it saves power and is fast. For example: it has built-in 16 analog sensors and 54 digital sensor interfaces, and supports USART and other communication modes. Arduino Mega 2560 has many features that other boards do not have. Why choose Arduino Mega? The main reason is that this board is more convenient for expansion. There are cheaper Arduino boards on the market. ![]()
