So I think it would be good if m5stack solves it that way.
between the Core 2 and the bottom comes an adapter with longer pins. Then I put the old modules and underneath the old module a base into which the micro module with mic and MPU6886 can be plugged.
- so I don't loose the two components of the micro module.
- i can use the old modules as long as they are pin compatible.
- i don't have to rebuild every old module as a new micro module and buy it before everything else !
