ESP32-WROVER-IE with ESP-AT

[DexterM]

I see that WROVER-32 is not recomended (in factory_param_data.csv). What about WROVER-IE? Is it recommended? What module_name should be used while installation for WROVER-IE?
Is it better to use WROOM-32UE or WROVER-IE?

Hi @DexterM , ESP32-WROVER series (includes ESP32-WROVER-E, ESP32-WROVER-IE, deprecated ESP32-WROVER-32) is not recommended for new design, mainly for the following reasons:

• Low performance requirements for ESP-AT: The ESP-AT solution itself does not require a more powerful chip.

• ESP32-WROVER series is better suited as a main controller: ESP-AT is typically used as a slave device, controlled by a main MCU through AT commands. ESP32-WROVER series, with its richer resources such as PSRAM and dual-core CPU, is generally better suited as a main controller.

• Cost considerations: ESP32-WROVER series is more expensive than the ESP32-C series. For mass production, the ESP32-C series offers better cost efficiency.

Thank you for your interest and support for ESP chips and the ESP-AT solution!
