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 nucleo...

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. Stm32duino lowpower and arduino IDE : #include "STM32LowPower.h" void setup() { GPIO_InitTypeDef GPIO_Init...

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, w...
