Espressif Systems ESP32-WROOM-32 MCU Modules
Espressif Systems ESP32-WROOM-32 MCU Modules are powerful and generic Wi-Fi/BT/BLE MCU modules that target various applications. These modules target applications ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding. The ESP32-WROOM-32U module is different from ESP32-WROOM-32D as it integrates a U.FL connector which needs to be connected to an external IPEX antenna.
The Espressif Systems ESP32-WROOM-32 MCU Modules use the ESP32-D0WD chip at the core. This SoC features two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80MHz to 240MHz. The 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.
