Question

Sensor tile footprint - pinout, pitch, etc ?

The only documentation on the Product Page is the Data Brief - which is extremely brief!

This marketing presentation gives overall dimensions (even those aren't in the Data Brief):

It tells us that it "can be soldered or plugged on a host board" - but there's no pinout or footprint details.

    That also gives only pinout - not pitch.

     

    PS:

    You added mention of the Gerbers.

    Yes, I'm sure it is in there - but, surely, this should be documented in the User Manual, or other human-readable document(s) ?

    Chip datasheets give dimensioned package drawings ...

      OK, so the Data Brief does mention UM2101:

      but not as a clickable link, and it is not mentioned on the Product Page

       

      UM2101 does give the pinout:

      but still not the pitch of the connections.
