Hi,  
Ref: assembly instruction sheet, Picture 22:  
The expander does not go to bottom, short of 2-3mm.  
How hard I can push the expander? Should it go to the bottom?  
Br, Martti

The V11 version of the SD extension board is not designed to fit into the bottom of the PI5 SD interface.

Please assemble everything correctly, and then insert the SD card with the operating system to see if the system starts up properly.
