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 practices for connecting the VBAT line to ensure proper operation and minimal noise?
In the attached schematic, I've connected VBAT to the battery cell and ground. Could you please review if this setup is correct for powering the circuit through VBAT? Also, is there anything else I should consider for stability or noise reduction and minimize the EMI/EMC issue?
