Module version??

[klaatu2]

How can I tell which ESP32-S3-WROOM-1 module I have?

There is no identification on the module:

From the outlook, there is no way to figure out the version. I think you need to check the sizes of flash and PSRAAM with software.

I have done the API route too. I'm not exactly sure, but it seems like the information is just being pulled from files rather than say from registers in the ESP32. THe output claims no PSRAM, yet this module is suppose to have 8MB

The version is printed on the module. (see images below)
THe module shows N16R8 = 16MB Flash, 8MB PSRAM.

But I still need a way for software to identify...or rather confirm the correct module has been loaded

Use any sketch you like (simpler is better). Open the serial monitor in Arduino IDE. Choose OPI PSRAM and Core Debug Level Verbose in the board menu. Upload the code. If you choose the wrong type of psram, it will boot loop. If you choose the right type of psram, you will be able to see the amount of SPIRAM (aka psram) listed near the end of the report.
