What are the differences between the modules ESP32-H2-WROOM-02C and ESP32-H2-MINI-1?

The title already states the question: What are the differences between the modules ESP32-H2-WROOM-02C-H4S and ESP32-H2-MINI-1-H4S?

There seems to be three different main types of modules around the ESP32-H2:

• ESP32-H2-WROOM-02C (Datasheet)
• ESP32-H2-MINI-1 (Datasheet)
• ESP32-H2-MINI-1U (Datasheet, see above)

Each main type comes with two different flash sizes (2MB or 4MB) which we may ignore for a moment. The MINI-1U has a connector for an external antenna and no PCB antenna. That's also obvious.

This leaves me with the differences between ESP32-H2-WROOM-02C and ESP32-H2-MINI-1.

A side-by-side comparison of both data sheets didn't seem to show any difference (or I missed) it. I have already tried Espressif's chat bot without success. The answer was:

The knowledge sources only contain information about the ESP32-H2-WROOM-02C module and do not include any details about the ESP32-H2-MINI-1. Therefore, I cannot provide a comparison between the two.

The pin layout and numbering seems to be different between both modules, but this can't be the only difference. Can it?
