Resolved! STLINK-V3MODS 3D IGS/STEP file
Title edited to "STLINK-V3MODS"Hello ST,Do you perhaps have an STEP or IGS file of the STMV3MODS module ?Thank a lot.
Resolved! NUCLEO-F446RE with steval-mic003v1: direct connection
Hello guys, I would like to know if it is possible to directly connect NUCLEO-F446RE board with steval-mic003v1 mic array without any expansion board. Would love to know your feedback and much appreciated.
Does STM32H747I-DISCO Comply with EMI/EMC Standards?
Hello everyone,I’m using the STM32H747I-DISCO development board for evaluation and prototyping. I would like to know whether this board has undergone any form of EMI/EMC certification (e.g., CE, FCC, CISPR) or internal EMI testing by ST.Specifically,...
Resolved! STM32H7B3I-DK – Shared GPIO pins (e.g. PA11/PA0, PC3/PD5) not working even when only one is used
On the STM32H7B3I-DK, several STMod+ signals share two GPIO options (e.g., PA11/PA0, PC3/PD5 for SPI2/USART2). Even when I configure only one of the shared pins as a simple GPIO (e.g., output or input with pull-up), it doesn’t function — no toggling,...
video camera module connection to STM32H745-Disco
we need to connect a camera to the STM32H745-Disco board. Our ultimate goal is to develop an application similar to the image_classification example from the STM32AI Model Zoo. Since we are unable to purchase another board, we would like to ask if it...
Resolved! SB configuration on nucleo-144
Hi,I'm trying to toggle a pin on my STM32H723 (LQFP144) using GPIO. According to the Nucleo-144 board datasheet, PE12, PE13, and PE14 appear to be connected to both CN10 (Zio) and CN12 (Morpho).However, when I toggle the pins to light up an LED, the ...
ESC PCB layout - B-G431B-ESC1
On the phase outputs why are there ground cutouts on the layout for this reference design. Is there a risk to cross couple to the ground plane with the switching noise or is it for thermal concerns?I've seen this in several ST ESC designs for drones ...
Resolved! direct SMPS Hardware design
Dear all!this is the first time i design PCB for STM32H755, as my understand for direct SMPS that i design like attach file, really i don't know is it correct, so can you help take look and let me know if any mistake.
Resolved! Nucleo ST-Link V3 holds board in reset when connected
Been working on the Nucleo H5 dev board for about a month. Everything with the built-in ST-Link/V3 was fine until randomly yesterday, the board would no longer get out of reset when the ST-Link is powered. Board powers up and boots if getting powe...
