I have made a demo board of STM32L476, to test power consumption in different mode. I have add a 10ohm resistor in vcc, calculating power consumption by measuring voltage in resistance.

demo board

lightsleep mode

deepsleep mode (below 1uA)

Cool, that would be:

9.54 mA in normal running mode
1.32 mA in lightsleep mode ?

What was the system clock setting ?
Which Micropython FW did you use for testing ?
