I am looking to extend battery life of the SensorTile.box PRO using sleep mode of STM32U5 and disabling the MEMS sensors. Currently I am measuring approx. 8 mA in this configuration, but I would like to reduce current into the uA range if possible.
I am running some quick tests in Arduino IDE using STM32duino libraries, but open to using Cube IDE as well:
LPS22DF.Disable();
LIS2MDL.Disable();
STTS22H.Disable();
LIS2DU12.Disable_X();
LSM6DSV16X.Disable_X();
LSM6DSV16X.Disable_G();
LowPower.deepSleep(1000);
Could you help me understand the source of the 8mA current draw? What other devices do I need to configure into sleep mode? Are there any firmware examples which put the SensorTile in low power sleep?
Thanks!
