Espressif ESP32-WROOM-32U 4M 32Mbit Flash WiFi Bluetooth Module
The ESP32-WROOM-32D and ESP32-WROOM-32U are powerful and versatile Wi-Fi, Bluetooth, and BLE MCU modules, engineered to support a wide range of applications. Whether it’s low-power sensor networks or high-demand tasks such as voice encoding, music streaming, and MP3 decoding, these modules deliver exceptional performance across various use cases.
The primary difference between the two modules lies in the inclusion of a U.FL connector in the ESP32-WROOM-32U, which offers greater flexibility in antenna connections. For detailed information about the U.FL connector and other technical specifics, please refer to Chapter 10 of the attached datasheet.
The datasheet contains comprehensive information applicable to both the ESP32-WROOM-32D and ESP32-WROOM-32U modules, and any differences between them will be clearly highlighted.
