  • The ESP-32F is a versatile WiFi-BT-BLE MCU module, powerful and versatile for use in low-power sensor networks and demanding tasks such as voice encoding, audio streaming and MP3 decoding.
  • This module is the core ESP32 chip, with scalable, adaptive features.
  • Two CPU cores can be individually controlled or powered on. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can cut off the power of the CPU and use low-power coprocessors to constantly monitor the state of the changes of peripheral or monitor whether certain analog values exceed the threshold.
  • ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet interface, high-speed SDIO, SPI, UART, I2S and I2C.
