NINA-B41-data sheet
The standby mode advertising and connected use cases described in Table 10 list the average
current consumption of a NINA-B41 module when using the typical configuration of a 1 s Bluetooth
advertising interval and a 50 ms connection interval.
Note Make sure that the configured output power of your product does not exceed the
maximum allowed limits of your intended target market(s), as described in the Regulatory
information application note [7].
