Can we program STM32F411RET6 with NUCLEO-L073RZ development board
Hi,We have made a PCB with STM32L073RZT6 and programming it with NUCLEO-L073RZ and it works well.Now we are testing with STM32L152RET6 and STM32F411RET6.STM32L152RET6 is getting programmed and works well with NUCLEO-L073RZ but not STM32F411RET6.Is ...

Is there a difference between WKUP1, WKUP2 and WKUP3 pin at STM32F373xx?
The data sheet of the STM32F373xx (https://www.st.com/resource/en/datasheet/stm32f373cc.pdf) on page 71 (6.3.6 Wakeup time from low-power mode) states that the WKUP1 (PA0) pin is used to wake up from standby mode. The reference manual (https://www.st...
STM32L152 comparator pulldown resistor inaccurate?
Is it possible that STM32L152RE's COMP1 400KOHM is actually ~330KOHM? I have tested it on 3 different hardwares and all brought me to this conclusion.
