Option 1
Description:
ESP32-WROOM-32 is a general-purpose Wi-Fi BT BLE MCU module with powerful functions and a wide range of uses. It can be used for low-power sensor networks and demanding tasks, such as voice coding, audio streaming, and MP3 Decoding etc.
The core of this module is the ESP32-D0WDQ6 chip x , which is scalable and adaptive. The two CPU cores can be controlled separately. clock
The frequency adjustment range is from 80 MHz to 240 MHz. The user can cut off the power of the CPU and use the low-power co-processor to continuously monitor the peripherals
The status change or whether some analog quantity exceeds the threshold. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors,
Low noise sensor amplifier, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C, etc.
The module integrates traditional Bluetooth, low-power Bluetooth and Wi-Fi, and has a wide range of uses: Wi-Fi supports a wide range of communication connections, and also supports
The router is directly connected to the Internet; while Bluetooth allows users to connect to mobile phones or broadcast BLE Beacon to facilitate signal detection. Sleep of the ESP32 chip
The current is less than 5 µA, making it suitable for battery-powered wearable electronic devices. The data transmission rate supported by the module is up to 150 Mbps, antenna output
The power reaches 20 dBm, which can achieve the widest range of wireless communication. Therefore, this module has industry-leading technical specifications,
Excellent performance in terms of transmission distance, power consumption, and network connectivity.
The operating system of ESP32 is freeRTOS with LwIP, and TLS 1.2 with hardware acceleration is built-in. The chip also supports OTA encryption
Upgrade, it is convenient for users to continue to upgrade after the product is released.

The core of this module is the ESP32-D0WDQ6 chip x , which is scalable and adaptive. The two CPU cores can be individually controlled or powered on. The adjustment range of the clock frequency is from 80 MHz to 240 MHz. The user can cut off the power of the CPU, and use the low-power coprocessor to continuously monitor the status changes of the peripherals or whether certain analog quantities exceed the threshold. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C.
CPU and memory
ESP32-D0WDQ6 contains two low-power Xtensa® 32-bit LX6 MCUs. On-chip storage includes:
• 448 KB of ROM, used for program startup and kernel function calls.
• 520 KB on-chip SRAM for data and instruction storage.
• The 8 KB of SRAM in RTC, that is, RTC slow memory, can be accessed by the coprocessor in Deep-sleep mode.
• The 8 KB of SRAM in the RTC, that is, the RTC fast memory, can be used for data storage and accessed by the main CPU when the RTC is started in Deep-sleep mode.
• 1 kbit eFuse, of which 256 bits are the system MAC address and chip settings; the remaining 768 bits are reserved for user applications, which include Flash encryption and chip ID.
• ESP-WROOM-32 integrates 4MB of SPIFlash
