Hi andylinpersonal,
The other difference is that ESP32-S3-WROOM-2 modules have a newer a version of ESP32-S3 chip inside.

Thanks. Do they have any breaking change we should pay extra attention to if we tried to develop with newer ESP32-S3-DevKitC-1-N32R8V but integrating ESP32S3-WROOM-1U-N16R8 into our final products?

I missed the key difference. WROOM-2-N16R8V has octal flash and WROOM-1U-N16R8 has quad flash.
Sorry for that.

ESP32-S3-WROOM-2 modules have octal flash and PSRAM.

By comparison, ESP32-S3-WROOM-1 modules have quad flash and either quad or octal PSRAM.
