#ARDUINO MEGA 2560 PIN LIST SERIAL#

Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 boards) programmed as a USB-to-serial converter. The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.

If using more than 12V, the voltage regulator may overheat and damage the board. 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. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.ĭigital I/O Pins 54 (of which 14 provide PWM output)įlash Memory 256 KB of which 8 KB used by bootloader 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.

#ARDUINO MEGA 2560 PIN LIST SERIAL#

It has 54 digital input/output pins (of which 15 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. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.
