Re: 32.768 Crystal specifications
Normally I would look at the Product Page for the Grand Central and follow the Downloads link to the github repo. In this case after searching through the Eagle SCH and BRD files I found some info, but it is not conclusive. I'll ask that engineering verify, but I think it could be the NX3215SA.
