Arduino UNO SMD (RS Part Number:769-7409)

This is a reference design of Arduino UNO SMD. The Arduino UNO SMD was converted into DesignSpark PCB format. Download link of the project files and introduction of Arduino UNO SMD could be found in this datasheet.

The Arduino Uno is a microcontroller board based on the ATmega328. 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 Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. Two versions are available differing only in the MCU package style: DIP or SMD. The Rev3 part has some minor pin changes.
