Vin : Input voltage of the Arduino board when using an external source (unless there is a 5 volt voltage on the USB connection or from another power source).Usually used to connect a reset button on an expansion board, which prevents access to the button on the Arduino board itself.
Reset - A low signal level at the pin reboots the microcontroller. AREF - Voltage reference for analog inputs. As standard, the pins have a measuring range of up to 5 V with respect to ground, however it is possible to change the upper limit by means of the AREF pin and function analogReference(). The Mega2560 platform has 16 analog inputs, each with a resolution of 10 bits (i.e., it can accept 1024 different values). With PWM, you can also use digital ports to control the power of connected devices. This means that you can only read and apply two kinds of signals to them: HIGH and LOW. Pins 0 (RX) and 1 (TX) are connected to the corresponding pins of the ATmega16U2, which acts as a USB-UART converter. #Arduino mega pinout serial#
These pins are used to receive (RX) and transmit (TX) data over the serial interface. SPI commutation pins (use the SPI library).
TWI / I☬ : pins 20 ( SDA ) and 21 ( SCL )įor communication with peripherals using a synchronous protocol, via 2 wires. Pull-up resistors are connected to the contacts, which are disabled by default, but can be enabled by software.Īllow 8-bit analog values to be output as a PWM signal.ġ6 analog inputs, each of which can represent analog voltage as a 10-bit number (1024 values). ICSP Connector for ATmega16U2 - ICSP connector for in-circuit programming of the ATmega16U2 microcontroller. SPI lines are brought out to a 6-pin connector, and are also duplicated on digital pins 50 (MISO), 51 (MOSI), 52 (SCK) and 53 (SS). Also, using the SPI library, these pins can communicate with expansion boards via the SPI interface. ICSP Connector for ATmega2560 - The ICSP connector is for in-circuit programming of the ATmega2560 microcontroller. Connector for external power supply - Connector for connecting an external power supply from 7 V to 12 V. USB Type-B connector - The USB Type-B connector is designed to flash the Arduino Mega 2560 platform using a computer. ON - Availability of power to the Arduino Mega 2560. When set to HIGH, the LED turns on, when set to LOW, it turns off. RX and TX - Flashes when communicating between the Arduino Mega 2560 and the PC. #Arduino mega pinout drivers#
The 16U2 firmware uses standard USB-COM drivers - no external drivers are required. When connected to a PC, the Arduino Mega 2560 is defined as a virtual COM port.
Microcontroller ATmega16U2 - The ATmega16U2 microcontroller provides communication between the ATmega2560 microcontroller and the USB port of the computer. It provides 256KB of flash memory for storing firmware, 8KB of SRAM and 4KB of non-volatile EEPROM for data storage. ATmega2560 Microcontroller - The heart of the Arduino Mega 2560 platform is the 8-bit AVR microcontroller, the ATmega2560. ĭescription of the elements of the Arduino Mega 2560 board #Arduino mega pinout install#
For the CH340G USB bridge chip, you need to install drivers on your computer, which can be downloaded here. All elements of external connections, including the names of ports, on this board fully correspond to the schematic diagram of the original board. The main differences from the original are due to the fact that a USB bridge is used to reduce the cost of the board, it is made on a budget CH340G microcircuit. This board has all the features of the classic Arduino Mega 2560 Rev3 board. By flashing this microcontroller, the controller can be used as a keyboard, mouse or game joystick.ĥ4 (14 of which can function as PWM outputs)Ģ56 KB (of which 8 KB are used for bootloader) The ATmega16u2 microcontroller allows the Arduino Mega2560 controller to be used as a USB HID device. The Rev3 version includes an Atmega16U2 chip (Atmega8U2 in Rev1 and Rev2 versions) with a USB to Serial converter firmware instead of those used in more early versions of FTDI chips. The Arduino Mega 2560 Rev3 is the latest model to replace the previous Arduino Mega 2560 and Mega 1280. Arduino Mega 2560 is compatible with all expansion boards designed for Arduino Uno or Duemilanove platforms. To work with Mega 2560, you need to connect the platform to your computer using a USB cable or supply power using an AC / DC adapter or a rechargeable battery. Arduino Mega 2560 is an extended version of the Arduino Uno built on the ATmega2560 microcontroller, has more contacts - 54 digital I / Os (14 of which can be used as PWM outputs), 16 analog inputs, more hardware serial ports - 4 serial UART ports, crystal oscillator 16 MHz, USB connector, power connector, ICSP connector and reset button.
