The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. 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. 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 2560 board is compatible with most shields designed for the Uno.Features:MicrocontrollerATmega2560Operating Voltage5VInput Voltage (recommended)7-12VInput Voltage (limit)6-20VDigital I/O Pins54 (of which 15 provide PWM output)Analog Input Pins16DC Current per I/O Pin20 mADC Current for 3.3V Pin50 mAFlash Memory256 KB of which 8 KB used by bootloaderSRAM8 KBEEPROM4 KBClock Speed16 MHzLED_BUILTIN13Length101.52 mmWidth53.3 mmWeight37 g
