Camera & Audio Media Board - FireBeetle Covers Camera
DFRobot FireBeetle series are low-power consumption development modules designed for Internet of Things (IoT). The FireBeetle Covers-Camera & Audio Media Board is a multimedia device for IoT that provides interfaces to connect NAU8822 CODEC IIS, OV7725 camera, SD card (SDIO), earphone, and microphone.
It is equipped with a mini MIC input interface. The NAU8822 CODEC IIS can drive both 12@8Ω BTL loudspeaker and 40mW@16Ω earphone. Direct connection is supported. Meanwhile, NAU8822 supports DAC sound signal acquisition and a programmable microphone amplifier. Recording is available when input voices with onboard MIC interface or microphone are saved to the SD card. Photo capture is available when connected to an OV7725 camera.
Function Diagram

With any FireBeetle main boards (e.g. ESP32 main board), the FireBeetle Covers-Camera & Audio Media Board can function as an MP3 player, recorder, or camera. Once connected to the Internet, it can be used as an Internet radio or for cloud image recognition.
NOTE: This media board only supports the FireBeetle ESP32 main board at present, as other boards do not have an IIS interface. The flat ribbon cable of the camera is relatively fragile—please connect carefully. The camera lens must face opposite the SD card slot. Video shooting and transmission are not supported.
