1.2 Description
ESP32-WROOM-32E and ESP32-WROOM-32UE are two powerful, generic Wi-Fi+BT+BLE MCU modules that
target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks,
such as voice encoding, music streaming and MP3 decoding.
ESP32-WROOM-32E comes with a PCB antenna, and ESP32-WROOM-32UE with an IPEX antenna. They both
feature a 4 MB external SPI flash. The information in this datasheet is applicable to both modules.
The ordering information of the two modules is listed as follows:
