ESP32-WROOM-32D is a powerful, generic Wi-Fi+BT+BLE MCU module that targets 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-32D is the most similar to ESP-WROOM-32 since it also comes with a PCB antenna, while ESP32-WROOM-32U is much smaller as it relies on an external WiFi/Bluetooth antenna via a u.FL connector. Both new modules are pin-to-pin compatible with ESP-WROOM-32
At the core of this module 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.
