Key Features


  • USB power input
    • Provides power supply to the whole system.
    • It is recommended that the system be connected to a power adapter for sufficient current supply.
  • Battery interface
    • Provides power supply to the whole system when the USB power interface is not used
    • The development board integrates the AP5056 power management IC to support battery charging.
  • Power switch
    • Turn on the switch and the system will be powered on.
    • Turn off the switch and the system will be powered off.
  • IS port
    • An IS bus transmits audio data between ESP32 and the DSP.
  • ESP32-WROVER-B module
    • This is a powerful, general-purpose, Wi-Fi+BT+BLE MCU module, targeting a wide
      variety of applications ranging from low-power sensor networks to the most demanding
      tasks, such as voice encoding, music streaming and MP3 decoding.
  • MicroSemi DSP
    • This audio co-processor is used for Automatic Speech Recognition (ASR) applications. It
      captures audio data from an external microphone array and outputs audio signals
      through its Digital-to-Analog-Converter (DAC) port.
  • IC/SPI port
    • ESP32, as an IC master, can access slave devices via the IC bus.
    • ESP32, as an SPI master, can access the DSP to read/write data via the SPI bus.
  • Earphone jack
    • Used for plugging in earphones.
  • Dual speaker output port
    • Supports two external speaker outputs.
  • Audio driver
    • This audio power amplifier sends audio signals from the DSP to external speakers for playback.
  • DC-DC boost power supply
    • This fixed-frequency DC-DC voltage booster powers the audio driver.
  • Micro SD card
    • The development board supports a Micro SD card in SPI/1-bit/4-bit modes, and can
      store or play audio files in the Micro SD card.
  • JTAG port
    • This standard JTAG interface is compatible with the ESP32 programming board and
      supports debugging functions.
  • CP2102N USB-UART Chip
    • An upgraded version of the CP2102 chip supports USB-to-UART conversion.
  • Programming port
    • This programming and debugging interface of ESP32 is compatible with the ESP32
      programming board.
  • USB Communication Port
    • This is a normal USB communication port between PC and ESP32 module.
