The DFRobot FireBeetle series comprises energy-efficient development modules specifically designed for the Internet of Things (IoT). One of these modules is the FireBeetle Covers-Camera & Audio Media Board, a versatile multimedia device for IoT applications. It offers various interfaces to connect components such as the NAU8822 CODEC IIS, OV7725 camera, SD card (SDIO), earphone, and microphone.

Additionally, this media board features a mini MIC input interface. The NAU8822 CODEC IIS is capable of driving both a 12W BTL loudspeaker at 8Ω and a 40mW earphone at 16ohm. It supports direct connections for easy integration. Furthermore, the NAU8822 supports DAC sound signal acquisition and a programmable microphone amplifier. This allows for audio recording when input voices are provided via the onboard MIC interface or an external microphone, with the ability to save the recordings to an SD card. Moreover, when connected to an OV7725 CAMERA, the board enables the functionality to capture photos.

With any FireBeetle main boards (e.g. ESP32 main board), the FireBeetle Covers-Camera & Audio Media Board could be a MP3, a recorder, a camera. Once connected to the Internet, it could be an Internet radio, a cloud image recognition.

  • This media board only supports FireBeetle ESP32 main board at present, for other main boards do not equipped with IIS interface.
  • The flat ribbon cable of camera is relatively easy-to-break, please be careful and light in connection. The camera shot must be opposite to the SD card slot.
  • It does not support video shooting and transmission.
