The Blues Swan datasheet provides overall dimensions for the board, but I would like to know the pads’ size (width and length) and distance between pads.  
Thank you!

Hi @RobLauer ,  
Thank you  
I’m designing a board that will carry the Swan and other components, so I will need exact dimensions.  
Thanks again.

Sorry - I had completely forgotten that the Swan schematics are available here in github, hope this helps: [note-hardware/Swan/v3.0/Feather at master · blues/note-hardware · GitHub](https://github.com/blues/note-hardware/tree/master/Swan/v3.0/Feather)

Thanks @RobLauer ,  
I have already checked those files on GitHub but couldn’t open the brd file to check the dimensions.

Was there a problem with the brd file?

Actually, I tried to open it in Kikad and Altium Viewer but couldn’t.  
That’s why I asked for the dimensions here, in case someone was able to open the file.

Thank you

Hi @Med_Tronic,

We recommend using the [OrCAD/Allegro PCB Free Viewer](https://www.ema-eda.com/how-to-page/how-to-use-the-orcad-allegro-pcb-free-viewer/) (though I believe it might be Windows-only).
