Reference Design of Arduino Nano 3.0

The reference design of Arduino NANO 3.0 (RS Part Number: 696-1667) was converted into DesignSpark PCB format and you may download the project’s files and BOM list in the Download section at the bottom.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has similar functionality to the Arduino Duemilanove, but in a DIP module package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.

• ATmega328 microcontroller with pre-programmed bootloader
• Input Voltage (recommended): +7 to +12V
• Input Voltage (limits): +6 to +20V
• 32KB Flash Memory (of which 2KB used by bootloader)
• 2KB SRAM
• 1KB EEPROM 
• Clock Speed: 16MHz

What is DesignSpark PCB?

DesignSpark PCB is an award-winning software package for schematic capture and PCB layout, available for FREE from RS Components. Our software is easy to learn and use yet surprisingly powerful. DesignSpark PCB is now widely adopted in the industry as a standard format for design file sharing and collaboration. This is especially useful in the prototyping phase where most of the innovation takes place. Not yet a DesignSpark PCB user?
