Features:

1.The main body of the module is the ESP-WROOM-32 module, and the peripheral uses the USB serial port chip CH9102 to expand the micro USB interface. It can be directly debugged through a USB connected computer, ensuring fast and stable data transmission and normal serial communication.

2.It has indicator lights on it, so you can always know the status of the module, support automatic download, and do not need to manually switch between download and running modes.

3.There are two touch buttons, one is reset, and the other is to enable the module to enter program mode. The pins on both sides of the development board are convenient for developers to connect and use.

4.The module has powerful Bluetooth compatibility and WiFi functions. As a development board that is compatible with Bluetooth and WiFi, it can obtain rich resources from the official website.

5.This module supports development on Windows systems (Cygwin and MSys32 simulation environments) and Linux systems, expanding the range of available resources and greatly improving the ease of learning and development. Of course, it can also be widely used in IoT applications, such as home automation, wireless industrial control, wireless positioning system signals, etc.

Product Introduction:

ESP-WROOM-32 is a universal Wi Fi+BT+BLE MCU module with powerful functions and a wide range of applications. It can be used for low-power sensor networks and extremely demanding tasks such as voice encoding, audio streaming, and MP3 decoding.

The core of this module is the ESP32-D0WDQ6 chip, which has the characteristics of scalability and adaptability. Two CPU cores can be individually controlled or powered on. The adjustment range of clock frequency is from 80 MHz to 240 MHz. Users can cut off the power supply of the CPU and use low-power coprocessors to continuously monitor the status changes of peripherals or whether certain analog quantities exceed the threshold. ESP32 also integrates a variety of peripherals, including capacitive touch sensors, Hall sensors, low noise sensing amplifiers, SD card interfaces, Ethernet interfaces, high-speed SDIO/SPI, UART, I2S, and I2C.

CPU and memory:

ESP32-D0WDQ6 comes with two low-power Xtensa built-in ® 32 bit LX6 MCU.

On chip storage includes:

1.448 KB ROM for program startup and kernel function calls.

2. 520 KB on-chip SRAM for data and instruction storage.

3. The 8 KB SRAM in RTC, also known as RTC slow memory, can be accessed by the coprocessor in deep sleep mode.

4. The 8 KB SRAM in RTC, also known as RTC fast memory, can be used for data storage and access by the main CPU during RTC startup in deep sleep mode.

5.1 kbit eFuse, where 256 bits are system specific (MAC address and chip settings)； The remaining 768 bits are reserved for user applications, including Flash encryption and chip ID.
