ESP32 Development Board WiFi+Bluetooth Dual Core Module ESP-WROOM-32 CH9102 38P

 
Product features:
1.The module body for the ESP-WROOM-32 module, peripheral USB serial chip CH9102 extended micro-USB interface, can be directly debugged through the USB-connected computer, fast and stable data transmission, to ensure the normal communication of the serial port .
2. It has indicator lights on it, so you can always know the status of the module, supports automatic download, no need to manually switch between download and run mode.
3. There are two touch buttons, one is for reset and the other is to enable the module to enter the program mode. The pins on both sides of the development board are easy for developers to connect and use.
4.The module has powerful Bluetooth compatibility and WiFi function, as a Bluetooth and WiFi compatible development board, it can get rich resources from the official website.
5. The module supports development on Windows (cygwin and msys32 emulation environments) and Linux systems, which extends the scope of its available resources and greatly improves the ease of learning and development. Of course, it can also be widely used in IoT applications, such as home automation, wireless industrial control, and wireless positioning system signals.

Product Description:
ESP-WROOM-32 is a general-purpose Wi-Fi+BT+BLE MCU module, which is powerful and versatile enough to be used in low-power sensor networks and demanding tasks, such as voice encoding, audio streaming and MP3 decoding.
The core of this module is the ESP32-D0WDQ6 chip, which is scalable and adaptive. The two CPU cores can be individually controlled or powered up. The clock frequency can be adjusted from 80 MHz to 240 MHz, and the user can power off the CPUs and use the low-power co-processor to constantly monitor the status of peripherals or whether certain analog quantities exceed the threshold. SPI, UART, I2S and I2C.

CPU and memory:
The ESP32-D0WDQ6 includes two low-power Xtensa® 32-bit LX6 MCUs.
On-chip memory includes:
1.448 KB of ROM for program startup and kernel function calls. 2.
2. 520 KB of on-chip SRAM for data and instruction storage. 3.
3. 8 KB of SRAM in the RTC, the RTC slow memory, which can be accessed by the coprocessor in deep-sleep mode. 4. 8 KB of SRAM in the RTC, the RTC slow memory.
4. 8 KB of SRAM in the RTC, the RTC fast memory, can be used for data storage and accessed by the main CPU when the RTC starts up in the deep-sleep mode.
5. 1 kbit eFuse, of which 256 bits are system-specific (MAC address and chip settings); the remaining 768 bits are reserved for user applications, which include Flash encryption and chip IDs.
6. ESP-WROOM-32 integrates 4MB of SPIFlash.
