WIRELESS & SENSING PRELIMINARY DATASHEET
To illustrate this process and the respective consumption in each mode, the CAD process follows the sequence of events
outlined below:
Figure 12. Consumption Profile of the LoRa CAD Process
The receiver is then in full receiver mode for just over half of the activity detection, followed by a reduced consumption
processing phase where the consumption varies with the LoRa bandwidth as shown in the table below.

4.1.5.1. Digital IO Pin Mapping
Six of RFM95/96/97/98(W)’s general purpose IO pins are available used in LoRa
TM
mode. Their mapping is shown
below and depends upon the configuration of registers RegDioMapping1 and RegDioMapping2.
