Power consumption for STM32L0 below 1mA #28
Description
Hi everyone,
I'm using stm32duino for STM32L0 for Dragino LSN50.
I use the variant B-L072Z-LRWAN1 as it is very similar to LSN50. The only difference are some SPI and LoRa pins.
I'm able to go down from 10mA in normal mode to 1mA in deep sleep / shutdown mode.
LoRa is not in used yet.
Is there anyway I should take note to go down bellow 1mA?
By right, the STM32L) should go to uA in deep sleep/shutdown mode?
Thanks a lot.
