Arduino Compatible Uno R3 SMD Board

Name : Arduino Compatible Uno R3 SMD Board

Color : Blue

The Uno R3 is an open source microcontroller board based on the ATmega328 chip. This board has 14 digital input/output pins, 6 analogue input pins, an onboard 16 MHz ceramic resonator, a USB connection port, an onboard DC power jack, an ICSP header, and a microcontroller reset button. It includes everything required to support the microcontroller. To get started, simply connect the board to a computer via a USB cable or power it via a DC adapter or battery. The Uno differs from all previous boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it has an Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. While the UNO can be powered via USB or an external power supply, the power source is selected automatically. External (non-USB) power can be supplied by either an AC-to-DC adapter (wall-wart) or a battery. Connect the adapter by inserting a 2.1mm center-positive plug into the board's power jack. Leads from a battery can also be inserted into the Power connector's Gnd and Vin pin headers. The board can be powered by an external supply ranging from 6 to 20 volts. However, if less than 7V is supplied, the 5V pin may supply less than five volts and the board may become unstable. When more than 12V is applied, the voltage regulator may overheat and damage the board. For Uno, the recommended voltage range is 5v to 12v. Specification
