Espressif ESP32-WROOM-32U 4M 32Mbit Flash WiFi Bluetooth Module
The ESP32-WROOM-32D and ESP32-WROOM-32U are versatile and robust Wi-Fi BT BLE MCU modules designed to cater to a broad spectrum of applications. From low-power sensor networks to high-demand tasks like voice encoding, music streaming, and MP3 decoding, these modules excel in various scenarios. The ESP32-WROOM-32U distinguishes itself from the ESP32-WROOM-32D by incorporating a U.FL connector. For comprehensive details regarding the UFL connector, please refer to Chapter 10 in the attached datasheet. It’s important to note that the information provided in the datasheet is applicable to both modules. Any discrepancies between them will be explicitly outlined within the document.
