Yeah that's not a problem, you only need to configure the accelerometer and then go to sleep, which is either System OFF mode or System ON mode(Idle).

There are examples that show how you can enter sleep and wake on pin.

Hey Håkon,

Thank you for your quick answer.

I'm getting more and more interested by this MCU and thus I need more informations.

Could I use an accelerometer in low power mode to turn on the MCU : I shake my device and then it starts.

Is that possible ?

Thank you

Hey Baptiste,

The nRF52840 can operate at 1.7v-5.5V so there's no problem in using a li-ion battery directly, but there's no built-in battery charger.

See Current consumption.
