Arduino UNO (SMD) 47pf 50V 0805 SMD Capacitor (Pack of 4000) Thermal Conductivity: 1Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input output pins, 6 Analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller that simply connects it to a computer with a USB cable or power it with an AC to DC adapter or battery to get started. The Arduino Uno is the successor to the Arduino Duemilanove
