Hello,

Please review my schematic. I am using STM32F030RCT6TR. I have attached screenshots of the schematic and the peripherals interfaced with it. Recommend EMI/EMC related suggestions.

NOTE: this STM will be controlled and is interfaced by ESP32 S3 for IO purpose by UART protocol. Following are the sections I have attached screen shots of:

STM32 controller IC

UART

RTC

WATCHDOG

DEBUG UART

DECAP

AND GATE IC

 

All suggestions/recommendations will be welcomed

Thank You!

The same answer applies here as well, which I already gave you in your other thread:

Your request for a review is not a request for help with a technical problem, but rather a classic request for an investigation into the device you developed. For such cases, there are companies that offer this kind of support, although it will not be free of charge.

However, you can contact an authorised distributor of your choice, who will be happy to help you further if the business case is sufficiently interesting.

Hope that helps?

Regards
/Peter
