I'm designing a custom PCB using the STM32F407G-DISC1 board as a reference, with the goal of meeting EMI/EMC standards. However, my design includes a VBAT connection from external battery that the reference board doesn't have. Can you advise on best ...

I am designing a custom board based on the STM32F407G and need to provide backup power to the VBAT pin using an external battery. my board board must comply with EMI/EMC standards, what are the key requirements and design considerations when connecti...

I would like to know if the STM32F407G-DISC1 development board has a dedicated VBAT pin for powering the internal RTC, allowing it to maintain time even when the board is not connected to power. If there is no VBAT pin on the development board, does ...
