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

Which software was used to design the PCB file
August 25, 2019 08:44
@PrideGandah V8 I would presume based on the dates of other comments posted. Are you having issues opening the PCB file?

22pf capacitors are connected to 5v or ground?

@Uzair1 Here is a link to an app note on hardware design for AVR microcontrollers, including details on the oscillator circuit and crystal / resonator selection: https://www.microchip.com/wwwAppNotes/AppNotes.aspx?appnote=en591472

@Uzair1 I don't see any discrete 22pf capacitors in the design. Based on the value, I presuming you are asking about load capacitors for the oscillator circuit. They usually go to ground. In this design, a ceramic resonator is being used with the oscillator, and this particular resonator (CSTCE16M0V53A-R0) has the load capacitors built in, going to ground. -Brad

Hi torontofred, this is because the downloaded files get prefixed with addition text.
e.g. prj file downloaded is in my case
3de52168-b551-11e6-96d7-bc764e08d8ff_Arduino Nano2.prj
Delete all the text just leaving "Arduino Nano2.prj"
repeat for the other files.
Copy the newly named files to a folder and then it opens in any version.

I cannot open the files with DesginSpark 8.0. Any suggestions?

Thank you for publishing this.. When I checked, the distance between two opposite pins such as d12 and d13 should be 15.24 and when I opened the PCB it shows 15.1? It might create problems when inserting a shield or into a breadboard?

@arundale I have referred this to the team to review the PCB. Thank you for your feedback.
