Arduino Mega 2560
This arduino mega 2560 microcontroller board based totally on the atmega2560. This board has fifty four digital I/O pins (of which 14 may be used as pwm outputs), 4 uarts (hardware serial ports), 16 analog inputs,a 16 mhz crystal oscillator, an icsp header,a usb connection, a energy jack, and a reset button. It incorporates the whole thing needed to aid the microcontroller; definitely connect it to a pc with a usb cable or energy it with a ac-to-dc adapter or battery to get started out. The mega is well matched with shields which designed for the Arduino duemilanove or diecimila.
The mega2560 different from all previous boards in that it does not use the FTDI usb-serial motive force chip. As a substitute, it capabilities the Atmega8 programmed as a usb-serial converter and has a resistor pulling the 8U2 HWB line to floor, making it simpler to put into DFU mode.
