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 adaptor or battery to get started.\n\nThe Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. \n\n--Microcontroller ATmega328\n\n--Operating voltage 5V\n\n--Input voltage range nom. 7-12V\n\n--Maximum supply voltage 20V\n\n--Digital I/O pins 14 (of which 6 provide PWM output)\n\n--Analog input pins 6\n\n--DC Current per I/O pin 40 mA\n\n--DC Current for 3.3V pin 50 mA\n\n--Flash mem;
