The ESP-WROOM-32 is a universal wi-fi + BT + BLE MCU module with powerful functions and a wide range of uses. It can be used in low -power sensor networks and demanding tasks, such as voice encoding, audio streaming, and MP3 decoding, and so on.

The core of this module is the ESP32-D0WDQ6 *chip, which is scalable and flexible. Both CPU cores can be individually controlled or powered. The clock frequency adjustment range is from 80MHz to 240MHz. Users can cut off CPU power and use a low -power coprocessor to continuously monitor device status changes or whether a certain analog quantity exceeds a threshold.
The ESP32 also integrates a variety of equipment, including capacitive touch sensors, hall sensors, low noise sensor amplifiers, SD card interfaces, Ethernet interfaces, high -speed SDIO/SPI, UART, l2S and I2C, etc.

CPU and memory:
The ESP32-D0WDQ6 is built into two low-power Xtensa 32-bit LX6MCUs. Storage on the chip includes:
● 448KB ROM, used for program startup and kernel function calls.
● 520 KB on SRAM chip for data storage and instructions.
● 8KB SRAM in RTC, i.e. RTC slow memory, can be accessed by coprocessor in deep sleep mode.
● 8KB SRAM in the RTC, which is the RTC’s fast memory, can be used for data storage and accessed by the main CPU when the RTC starts in deep sleep mode.
● 1 eFuse bit, of which 256bit is dedicated to the system (MAC address and chip settings); The remaining 768 bits are reserved for user applications, including flash encryption and chip IDs.
● ESP-WROOM-32 integrates 4MB SPIFlash
