Introduction: The ESP-32F is a universal WiFi-BT-BLE MCU module that is powerful and versatile for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding. The core of this module is the ESP32 chip, which is scalable and adaptive. Two CPU cores can be individually controlled or powered up. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can power off the CPU and use a low-power coprocessor to constantly monitor the status changes of the peripherals or whether certain analogs exceed the threshold. The ESP32 also integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, low noise sense amplifiers, SD card interfaces, Ethernet interfaces, high speed SDIO, SPI, UART, I2S and I2C. The ESP-32F integrates traditional bluetooth, bluetooth low energy and Wi-Fi for a wide range of uses: Wi-Fi supports a wide range of communication connections and direct Internet connection via a router; bluetooth allows users to connect to mobile phones or broadcast BLE Beacon for signal detection. The ESP32 chip' s sleep current is less than 5 μ A, making it suitable for battery-powered wearable electronics. The ESP-32F supports data rates up to 150 Mbps and a power amplifier with an output power of 22 dBm for maximum wireless communication. As a result, the chip has industry-leading specifications and performs in terms of high integration, wireless transmission distance, power consumption, and network connectivity. The ESP32' s operating system is a freeRTOS with LWIP and TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrades, and developers can continue to upgrade after the product is released.
