In addition to the "SNAPZZ magnetic" Experiment i am looking into mechanical Lock/Release Systems. I found this tiny nice one that i can use. For ver permanent Installations, a Solder-standoff and a screw is the better choice; For Experimenting, debugging, swapping a Quick-Release Model is better.

The Module itself doesn't need a change, the Notch on Top can stay there and swapped into a Carrier board with a Screw. The Carrier Module (depending on the Quick Lock).

Modules with a SNAPZZ...
