Note that these pins are not in the same location as the TWI pins on the old Duemilanove or Diecimila Arduino boards. Support TWI communication using the Wire library. The controller provides 256KB of Flash memory for storing firmware, 8KB of SRAM, and 4KB of non-volatile EEPROM memory for data storage. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. ATmega2560 Microcontroller The heart of the Arduino Mega platform is an 8-bit AVR family microcontroller ATmega2560 with 16 MHz clock speed. There is a built-in LED connected to digital pin 13. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Arduino /Genuino Uno and the old Duemilanove and Diecimila Arduino boards. These pins support SPI communication using the SPI library. USB to TTL chip adopts more economic and stable CP2012.

SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). KEYESTUIDO Mega 2560 plus Board, whose processor core is ATMEGA2560-16AU, is fully compatible with ARDUINO MEGA 2560 REV3. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level.

Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2).

Used to receive (RX) and transmit (TX) TTL serial data.

Arduino mega 2560 uart pins update#

The Arduino Mega 2560 is an update of the. It’s perfect for use in 3D printing and robotics based projects. The Mega is designed to support more complex projects, in comparison to the UNO board which is more suitable for beginners. In addition, some pins have specialized functions: The Arduino Mega 2560 is a development board based on the ATmega2560 microcontroller. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V. This pin on the board provides the voltage reference with which the microcontroller operates. A 3.3 volt supply generated by the on-board regulator. Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). This pin outputs a regulated 5V from the regulator on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.ĥV. The input voltage to the board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source).
