Figure 7: Pin assignment
As described in the previous picture the BLUENRG-M2SA module is using exposed pad in order to allow
a full optical visual inspection in order to fulfill the needs of industrial grade applications.
The Table 4 provides the association between BLUENRG-M2SA module pin and the related BlueNRG-2
pin. Refer to the BlueNRG-2 datasheet for detailed description.
