Hello,I need to keep alive an RTC when the system is rebooted and I see there is VBAT pin in the MCU->Nucleo board which I understand is made for it. What I don't understand however is if in the Nucleo I should take out the 0Ohm resistor on SB52 or ...
We would like to integrate the following discovery board into a prototype.Could you please provide a 3D model of the STM32F469-DISCO board in .obj, .wrl or eventually .step format?
I have two custom boards with STM32G0B1 Chips. I am using an ST-Link V3 (V3J10M3 on Stm32CubeProgrammer - SWD default settings)to flash them.On the first board, I could connect, but on flashing it for the first time, it reported failed to erase memor...
Please help to provide soldering reflow profile of STM32G031K8U6. Thanks !
hello everyone I am new to this stm32 series i purchased the stm32g0b0ret6 controller and now i am using stlink version v2j40s0 but i am getting the error no target device found can anybody guide me for that
Hello,I am using STM32L412 Microcontroller in my current project.As shown in the attached image in the Application Note "AN4555" for STM32L412,For additional Precautions, VDD should be connected through Ferrite Bead at the VDDA pin.So, my question i...
I have a NUCLEO-L432KC like the title says and I want to power it from an external source. I am using the ST-Link debugger as an 8mhz clock input, and when the st-link is not powered it pulls the RST pin low and I don't get my 8mhz clock input. I hav...
what is U2A i see in top of the schematics?What is the diffrent between U2A and U7A? thanks
I have 11 boards of our prototype with the STM32L4A6AGI6 (i.e. 169 BGA) assembled. 5 of them work fine. The other 6 eventually loose debugging connection. It doesn't happen immediatelly i.e. I'm still able to run a few lines of code but then it reset...
