I see numerous references to ESP32-WROOM.

Does "WROOM" have a meaning, or is it just a marketing term for a particular version of the ESP32?

As best I can tell, it's merely a part number in the ESP32 family of parts. While there may be some hidden meaning, I suspect that it contains an English word to be a concidence.

Here is the set of ESP32 parts from Espressif Systems:
