Module order:

CNM-V1 (draws a lot of current, gives only low signal)
BSTD1-N (for height information)
CNM-V2 (works fine)
 

Attatchment 1: Stack config, beam from right. In the box the stack is mounted with the labelled side of the BSTD1-N module on top (90deg rotated w.r.t. photo)

Attachment 2: the top edges of the sensors coincide -> when the beam hits the last strips of the BSTD, it also hits the pitch adapter region of the CNM sensors
