Hi,

Is there a Cadence Allegro schematic/layout for mangoOH red PCBA? I cannot open the files available for download!

I see from discussion @  
[mangOH RED schematics file](https://mangoh.discourse.group/t/mangoh-red-schematics-file/912) that the files may be in Mentor expedition format !

I am reposting as this discussion was from last year. Any help appreciated!

Thanks, Arvind

Thanks for the note. Can you please provide the tool chain and version used to create schematic and layout? Also can you please update the [mangoh.io](http://mangoh.io) website with the correct cad tool description? At present the website labels these files as in Allegro/Orcad format.
