With this adapter, which fits very tightly in the SD version (sometimes you have to even rework some) are excluded this contact problems.
The locking mechanism for the micro SD pressed the card firmly on the contacts of the adapter so that it no Kontaktierungsproblemen comes here more, even strong vibrations, for example during operation in the car, are no longer a problem.
A pleasant side effect: the SD card is barely (about 1.2mm) out on the RP board, the risk that the card is damaged, no longer exists.
Small disadvantage, as others have mentioned: The adapter "bears down on something" ..., scarce housing then require some reworking (2mm well), so that the adapter fits in (or has a housing in which the RP is fastened with spacer bolts on the housing that best suits ...).
