Suggestion for Battery Power Application
Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz
crystal and 2 capacitors on host board. The 32MHz main clock won’t be active at idle state to save power.
Two inductors required for on-board DC to DC converter are inside BT840F. You can enable DCDC converter
to have lower power consumption.
