Dear ST Support Team,I am using the STM32H7 Nucleo-144 (MB1364) board mounted as a shield on my custom hardware board.I would like to power the Nucleo board directly from my carrier board through the Arduino connectors.Could you please confirm the following points?Is it possible to power the Nucleo board by supplying 5 V through the Arduino connector? Is it possible to power the Nucleo board by supplying 3.3 V through the Arduino connector? Are there any specific jumper settings, protections, or precautions that should be considered, particularly regarding the USB/ST-LINK power supply? What is the recommended method for powering the Nucleo board when it is integrated into a custom embedded system?Thank you in advance for your support.
