If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 6 to 20 volts. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino Mega can be powered via the USB connection or with an external power supply. You can also bypass the bootloader and program the microcontroller through the Cytron USB ICSP PIC Programmer header. The Arduino Mega2560 can be programmed with the free and open source Arduino IDE hrough a USB connection without needing any extra hardware thanks to its preburnt bootloader. For SPI communication, use the SPI library.

The Arduino software includes a Wire library to simplify use of the I2C bus see the documentation on the Wiring website for details. Furthermore, it supports I2C (TWI) and SPI communication. An ATmega8U2 on the board channels one of these over USB and provides a virtual com port to software on the computer.

The ATmega2560 provides four hardware UARTs for TTL (5V) serial communication. The Arduino Mega2560 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. It also has 16 analog inputs, each of which provide 10 bits of resolution (i.e. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.Įach of the 54 digital pins on the Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.

The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. The Arduino Mega can be powered via the 1.5m USB Cable Type A to B or with an external power supply. The Arduino Mega is compatible with most shields designed for the Arduino Uno, Duemilanove, or Diecimila. 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.
