Description

ESP32-WROOM-32D and ESP32-WROOM-32U are 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-32U is different from ESP32-WROOM-32D in that ESP32-WROOM-32U integrates a U.FL
connector. For detailed information of the U.FL connector please see Chapter 10. Note that the information in
this data sheet is applicable to both modules. Any differences between them will be clearly specified in the course
of this document. Table 1 lists the difference between ESP32-WROOM-32D and ESP32-WROOM-32U.

At the core of the two modules is the ESP32-D0WD chip that belongs to the ESP32 series* of chips. The chip
embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled,
and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power
co-processor that can be used instead of the CPU to save power while performing tasks that do not require much
computing power, such as monitoring of peripherals. ESP32 integrates a rich set of peripherals, ranging from
capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S and I²C.
