Funduino Mega 2560 ATmega2560-16AU Board (Arduino-compatible) + Free USB Cable
The Mega 2560 is a microcontroller board based on the ATmega2560 .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.The Mega 2560 is an update to the Arduino Mega, which it replaces.SummaryMicrocontroller:ATmega2560Operating Voltage:5VInput Voltage (recommended):7-12VInput Voltage (limits):6-20VDigital I/O Pins:54 (of which 14 provide PWM output)Analog Input Pins:16DC Current per I/O Pin:40 mADC Current for 3.3V Pin:50 mAFlash Memory:256 KB of which 8 KB used by bootloaderSRAM:8 KBEEPROM:4 KBClock Speed:16 MHz
