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.

Moreover, it equips with a mini MIC input interface. The NAU8822 CODEC IIS can drive both 12@8Ω BTL loudspeaker and 40mW@16Ω earphone. The direct connection is supported. Meanwhile, NAU8822 supports DAC sound signal acquisition and programmable microphone amplifier. The recording is available when input voices with onboard MIC interface or microphone then save it to SD card. What's more, the function to take photos is available when connected to an OV7725 CAMERA.
