Thanks to the ATmega2560 (and its associated crystal oscillator), the Arduino Mega sports 16 MHz clocking speed, as well as 256 KB of flash, 8 KB of SRAM and 4 KB of EEPROM. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. ![]() If you compare this table with the tables in Chapter 1 it is obvious that the basic capabilities of an Arduino board are the capabilities supplied by its microcontroller. The distribution of elements on the Arduino Mega 2560 - in the latest version of the board, reset button is near the USB connector. As stated before, the brain behind the Arduino Mega is the ATmega2560. Table 4-1 is a comparison of the most common Arduino board types. To help you get started with the module, we have prepared a tutorial about the installation and first run of the Arduino environment. The connected led on pin 13 allows debugging of simple programs.īuilt-in voltage regulator provides power to external devices with the voltage of 3.3 V with current consumption of 50 mA. Its design is based on the Arduino Mega2560so we can use it as a Arduino Mega2560 development board. The IOREF Pin provides direct access to the voltage with which I/O outputs work. The module has ICSP outputs for connecting an external AVR programmer. Arduino has a system that protects the socket from short-circuit and the flow of too large current. The tile can be powered from a computer via USB cable, bearing in mind that the maximum power load for the USB port is 500 mA. To power the Arduino, you can use any power source with a voltage from 7 V to 12 V with DC connector 5.5 x 2.1 mm. The Atmega2560 chip with a clock signal with a frequency of 16 MHz, has 256 KB Flash memory, 4 KB EEPROM and 8 KB SRAM memory. Some of the pins have special functions which brief description is available in our guide. The device supports popular network interfaces, including UART, I2C and SPI. ![]() to control the motors and for brightness control of the LEDs.ġ6 inputs of integrated analog-digital transmitter with a resolution of 10-bit, supports, in particular, sensors with analog output. Simply solder the DC-DC converter onto the breakout board as indicated. Thanks for referring to MEGA schematic which shows: Digital Pin-2. The maximum power load for a single output is 40 mA.ġ5 PWM outputs allow e. CrossRoads: What does the Mega schematic show. The first serial port (-1 or 0) will always be used by the Arduino. The distribution of connectors allows the installation of special caps, so-called Arduino Shield.ĥ6 digital inputs/outputs allows, in particular, to control the LEDs, relays and reading the buttons' states. Change this if, for example, you need to connect a wireless adapter to non-default port pins. Thanks to installed bootloader, to programm the device, you only have to use appropriate USB cable and software from manufacturer's website. ![]() Components for 3D printers constructionīelow are a few features that distinguish modules Arduino compared to other programmable tiles.Arduino Mega 2560 PIN mapping table A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. There are pin mappings to Atmega8 and Atmega 168/328 as well. Laser cutting machines - engravers, plotters Special functions, Some of the pins have special functions which brief description is available in our guide. Below is the pin mapping for the Atmega2560.I'm doing a project that reads nitrogen, phosphorus and potassium (NPK) with a NPK sensor and I want to upload it to Google sheets through the built-in ESP8266 but I don't know how can I send the data obtained on the MEGA to the ESP so I can upload it, I know that I have to send the data from one serial port to another so I can serial print the values on the ESP as the first step but I don't know how to continue, in the future I'll add coordinates and more info but I suppose that it's the same way.
