![]() ![]() 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 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. Arduino Mega 2560 Pinout Arduino Mega 2560 Pinout P. 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. ATmega2560 Microcontroller The heart of the Arduino Mega platform is an 8-bit AVR family microcontroller ATmega2560 with 16 MHz clock speed. 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. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Arduino Mega 2560 has many features that other boards do not have. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. ![]() Why choose Arduino Mega? The main reason is that this board is more convenient for expansion. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). Arduino Mega Pinout Voltage Regulator-The voltage regulator converts the input voltage to 5V. It has a crystal oscillator-16 MHz, a power jack, an ICSP header, a USB-B port, and a RESET button. There are cheaper Arduino boards on the market. Arduino Mega 2560 has 54 digital input/output pins, where 16 pins are analog inputs, 14 are PWM pins, and 6 are hardware serial ports (UARTs). ![]()
