![]() ![]() ![]() More information at the Arduino page here. This board offers several great functions such as:Īdditional features coming with this R3 version are:ĪTmega16U2 instead 8U2 as USB-to-Serial converter.ġ.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes. Pins on the chip and pins on the board are not the same thing. However in the schemati I2C bus seems to be on pins 43 and 44. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. Documentation seems to say that I2C bus uses pins 20 and 21. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. 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. Reset : It has reset circuit with capacitor, button and resistor to reset the controller. The Arduino Mega 2560 R3 is a microcontroller board based on the ATmega2560. Arduino Mega ICSP Pinout for ATmega 2560. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It makes a great controller board for RepRap. Tech Specs Compatibility Suggested Libraries The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The new Arduino Mega 2560 R3 is a microcontroller board which is an upgrade from the Arduino Mega. ![]()
