Mega AVR mega1280(Arduino Mega Compatible)

Introduction:
- DFRduino Mega is 100% same as the original Arduino Mega.
- The Arduino Mega is a microcontroller board based on the ATmega1280. 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 cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

Specifications:
- Microcontroller                               ATmega1280
- Operating Voltage                         5V
- Input Voltage (recommended)   7-12V
- Input Voltage (limits)                    6-20V
- Digital I/O Pins                              54 (of which 14 provide PWM output)
- Analog Input Pins                        16
- DC Current per I/O Pin                40 mA
- DC Current for 3.3V Pin              50 mA
- Flash Memory                              128 KB of which 4 KB used by bootloader
- SRAM                                             8 KB
- EEPROM                                       4 KB
- Clock Speed                                16 MHz

Shield Compatibility:
The Mega is designed to be compatible with most shields designed for the Diecimila or Duemilanove. Digital pins 0 to 13 (and the adjacent AREF and GND pins), analog inputs 0 to 5, the power header, and ICSP header are all in equivalent locations. Further the main UART (serial port) is located on the same pins (0 and 1), as are external interrupts 0 and 1 (pins 2 and 3 respectively). SPI is available through the ICSP header on both the Mega and Duemilanove / Diecimila. Please note that I2C is not located on the same pins on the Mega (20 and 21) as the Duemilanove / Diecimila (analog inputs 4 and 5).

The Mega is compatible with:
- Arduino Mega Prototype Shield
- Arduino I/O Shield
- Arduino LCD Shield
- Arduino Motor Shield

The Mega is NOT compatible with:
- Arduino Ethernet Shield
