ESP32-WROOM-32E Wifi and Bluetooth Module

Esp32 32 Bit 240Mhz PCB Antenna 4Mb Flash Dual Cpu Iot Home Automation Industrial Machine Control

     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.

     At the core of the module is the ESP32-D0WD-V3 chip*. 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.
