5.1 Power Supply

The BM83 module is powered through the BAT_IN input pin. The following figure illustrates the connection from the BAT_IN pin to various other voltage supply pins of the IS2083BM SoC on the BM83 module. The external 5V power adapter can be connected to ADAP_IN in order to charge the battery in battery powered applications or in USB applications. Otherwise the ADAP_IN pin can be left floating if there is no battery utilized at BAT_IN pin.
