Mega-2560 - microcontroller board
Arduino Mega 2560 Datasheet Overview The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet).
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 ACto-DC adapter or b
Mega-2560 Features
* the Atmega8U2 programmed as a USB-to-serial converter. The power pins are as follows:
* VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin,
