The sub-family variants primarily differ in antenna configuration, flash capacity, and integrated memory. Standard 'E' models feature an onboard PCB trace antenna, while 'UE' models provide a U.FL connector for external antennas. Flash memory options range from 4MB (N4) up to 16MB (N16) to suit application complexity. Some specific variants, such as the R2 models, include additional PSRAM to support memory-intensive tasks like audio buffering or local web hosting.
