Dear Sir
・I want to use NUCLEO-F446RE as a PoC for IoT.
・I plan to use alkaline batteries and connect to CH6 PIN4. (3.3V)
⇒It is necessary to reduce the current consumption.
I investigated with a simple FW.(Use stabilized power source(SPS))
Case:Run Mode(HCLK 180Mhz)
・current consumption
JP5：About 44mA
SPS：About 80mA
Case:Standby Mode(HCLK 180Mhz)
・current consumption
JP5：About Less than 1mA
SPS：About 40mA
・It turned out that the current consumption of SPS is large.
・At this time, LD1 was Slow blinking Red.
I guessed that the current consumption of SPS is large because ST-Link is running.
・Is this idea correct?
・Is there any other reason why the current consumption of SPS is large?
・If my opinion is correct, is there a way to turn off the power supply to ST-Link?
Regards
