The Arduino Compatible 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 an AC-to-DC adapter or battery to get started. Features : CH340G replace the Atmega 16U2 Microcontroller: ATmega2560 Clock Speed: 16 MHz EEPROM: 4 KB SRAM: 8 KB Flash Memory: 256 KB of which 8 KB used by bootloader Operating Voltage: 5V Input Voltage (recommended): 7-9V Analog Input Pins: 16 Digital I/O Pins: 54 (of which 14 provide PWM output) DC Current for 3.3V Pin: 50 mA DC Current per I/O Pin: 40 mA
