Hi there ,

I lose the date each time I shutdown the board down and unplug the USB-C PS.
It’s written : * RTC => RTC backup current is 0.25μA TYP (VDD =3.0V, TA =25℃).

does it mean I can put a CR2032 battery on this JST connector , and if not, what type of other power supply ?
thanks for your help

You can use CR2032 BAT.
