Package Included:1x Mega2560 R3 board1x USB cableIntroduction:The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. 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.It contains everything needed to support the microcontroller;simply connect it to a computer with a USB AC-to-DC adapter or battery to get started.The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.Specification:Microcontroller: ATmega2560Operating Voltage: 5VInput Voltage (recommended): 7-12VInput Voltage (limits): 6-20VDigital I/O Pins: 54 (of which 14 provide PWM output)Analog Input Pins: 16DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 256 KB of which 8 KB used by bootloaderSRAM: 8 KBEEPROM: 4 KBClock Speed: 16 MHzThis board is a clone of the original Arduino board
