Hi,
I'm developing a new product. I want to manage power ON/OFF with the button. I see 2 solutions.
1) Using a pushbutton controller (like ST SRC0) -> Adding 0.5$ to my BOM
2) Using system off mode of the NRF52 and detect button action on the GPIO to wake the processor.
As we want to supply with a CR2032 cell with at least one year of battery life, I want to be sure to have the best solution in terms of power management.
Which module is used to have the wakeup with GPIO and what is the associated power consumption when the process in this mode?
Thank you
