Arduino Mega 2560 R3 Board with ATmega2560 – Options
The Arduino Mega is a microcontroller board based mostly on the ATmega2560. It has 54 digital enter/output pins (of which 14 can be utilized as PWM outputs), 16 analog inputs, 4 UARTs ({hardware} serial ports), a 16 MHz crystal oscillator, a USB connection, an influence jack, an ICSP header, and a reset button. It comprises every thing wanted to help the microcontroller; merely join it to a pc with a USB cable or energy it with a AC-to-DC adapter or battery to get began. The Mega is appropriate with most shields designed for the Arduino Duemilanove or Diecimila.
The Mega 2560 R3 additionally provides SDA and SCL pins subsequent to the AREF. As well as, there are two new pins positioned close to the RESET pin. One is the IOREF that permit the shields to adapt to the voltage offered from the board. The opposite is a not linked and is reserved for future functions. The Mega 2560 R3 works with all current shields however can adapt to new shields which use these extra pins.
The mega 2560 is an replace to the arduino mega, which it replaces. The mega2560 differs from all previous boards in that it doesn’t use the ftdiusb-to-serial driver chip. As an alternative, it options the atmega16u2 (atmega8u2 within the revision 1 and revision 2 boards) programmed as anusb-to-serial converter.
