5.1.2 Mounting Holes
There are 2 x 2.3mm mounting holes on cB-0901. The reasons for the 2.3mm holes are that
the threaded M2 holes on the single and double row connectors (see section 5.2.1) are not
aligned. The outer tangents of the 2.3mm holes align the module if the single row connectors
are used and the inner if double row connectors are used (see Figure 6).
Choose the outer tangent (CC distance 27.24mm) if the module is aligned and mounted with
some other technique based on M2 screws (e.g. press-fit nuts), see Figure 7 and Figure 8.
