Arduino for STM32

hello
accurate measurement today with nucleo 64 F401 Re
Idc measurement on IDD jumper

with simple deep sleep call : 250µA
with port disable : 40µA.

Thus , black pill is low cost but not able to work in deep sleep mode : Schematic is not accurate.

It's better to build your own circuit or buy a ...

Hello
I don"t have exact black-pill schematic . I cut the 5v - 3v3 on board regulator : -3mA
I remove LED ( -0.5mA) : Idc=1mA now

I know that 0.3mA result from 10k pull up on boot switch.

next step will be on nucleo board with real schematic.

...

Merci Frédéric pour cette réponse.

I simply add this code in setup : always 4mA in deep sleep.
Maybe the IDEarduino setup add some wrong configuration.
i will try with a Nucleo board.

Hi
Blackpill stm32F401 deepsleep : 5mA !
I'm trying this simple example:

https://github.com/stm32duino/STM32LowPower/blob/main/examples/TimedWakeup/TimedWakeup.ino

with external 3v3 supply, I remove on board regulator , LED, I disconnect Tx RX line used for programming : no improvement

I see this ...
