STM32 MCUs Boards and hardware tools

How to protect GPIO input from voltages greather than 3.3V/5V being applied there?

Hi, I'm using the stm32F207Z mcu for input/outputs digital processing. Mcu will also handle the Ethernet communications. Our application will read logic levels from GPIO pins configured as inputs, but it is also able to write on other GPIO port confi...

STM32 Boards and USB Host issue

Hi,I'm trying to make a simple USB host for MSC devices. I'm working with a STM32F429 NUCLEO-F429ZI board and a STM32F407 STM32F407G-DISC1 boards.The matter is that both boards have USB power switches wih oppostie logic. That is, the Nucleo boards ha...

To create a Custom Break-out board/ Expansion board/ Shield for STM32 Nucleo-F303RE

For a new project, considering the fact that the microcontroller chips are currently not available immediately on distributor websites lately, I decided to create a break-out board/ Expansion board/ Shield for a STM32 nucleo board with just the perip...

i bought a stm32vldiscovery board from digikeys turkey distrubitor. my computer sees it but stlinkupgrade tells me it is not supported. is there a way to fix this or did i just bought a chunk of glorified useless silicon?

Can't get UART Loopback to work

Context:Coming from an arduino background, I wanted to further develop my MCU skills and also learn how to read datasheets and reference manuals more efficiently, so I got a NUCLEO-F767ZI board and my idea for a first "project" was to loopback UART ...

What is the exact model of "ST Zio" connector on NUCLEO-F767ZI??

I'm looking for connectors to populate CN11 and CN12 on the board, but all extended 2.54mm female connector I cound find have 11mm legs, those used by ST is only about 8.4mm.If they are not the same length, I won't be able to plug the board on other ...
