Reference Design of Arduino Nano 3.0




March 10, 2021 10:20

I am still unable to save and open the project file in version 9.0.4
I tried to change the name by removing all the information before "Arduino ...." but it still fails to open the Project and sheet 1 & 2
Please assist

@Techie_hobby1 Have you saved all the files in to a project folder? The file names in the project should be Sheet1.sch, Sheet2.sch, Arduino Nano2.pcb and Arduino Nano2.prj However as you also state you cannot save is your software still activated? Go to Help - About and you should have a serial number and activation code. If missing raise a support request and state your serial number to get an activation code.

Does not open with version 9

@albuckley I just checked and it does work in V9, are you removing the preamble the download files have attached to the filename? The suggested method is to download the files, then create a project folder and move the files to this folder. Rename the files by deleting everything on the left up to the underscore. Unfortunately this is due to the way the database and website functions and has to be done for all reference designs.

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.

Which software was used to design the PCB file

@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:

@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?
