Support ESP32INTRODUCTION: ESP-WROOM-32 is a general-purpose WI-FI+BT+BLE microcontroller module that can be used for low-power sensor networks and more demanding tasks, such as voice coding, audio streaming, and MP3 decoding. The module and core are ESP32-DOWDQ6 chips, which are scalable and adaptive, and the two CPU cores can be controlled separately or powered on. THE CLOCK FREQUENCY CAN BE ADJUSTED FROM 80MHZ TO 240MHZ. Users can cut off power to the CPU and use a low-power coprocessor to constantly monitor the status of peripherals for certain analog amounts that are above thresholds. ESP32 also integrates a rich set of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensing amplifiers, SD card interfaces, Ethernet interfaces, high-speed SDIOSPI, UART, I2S, and I2C, among others.CPU & Memory: The ESP32-D0WDQ6 contains two low-power XtensaB32-bitLX6 MCUs. On-chip memory includes: 448 KB of ROM for program boot and kernel function calls. 520KB on-chip SRAM for data and instruction storage.The 8KB of SRAM in the RTC, i.e., the RTC slow memory, can be accessed by the coprocessor in Deep-sleep mode. The 8KB of SRAM in the RTC, the RTC Fast Memory, can be used for data storage and access by the main CPU when the RTC is started in deep sleep mode. The board has a 1kbit 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. ESP-32 integrates 4MB of SPIFlash.
