Hi there,
Yea preaching to the quire here, No pins… 
However I did get some pins and a grove connector??(see Picture)
The 404 has been since it showed up on their linkd in page.
I bought a couple and got the schematic from support here.(Citric a.k.a full-service) 
pretty trick for just Digital io. or ONE grove connector to Go.
Check my other thread for more? EXPANDO
