Two-microphone wireless audio reference design kit
It includes two microphone boards, a receiver board with both USB and analog interfaces, plus a complete set of design files, source code, and supporting documentation. The microphone board integrates a Nordic nRF2460 2.4GHz audio streamer IC, AKM’s AK5700 16-bit mono ADC with microphone pre-amp and ALC (Automatic Loudness Control), a 3.5mm jack for the microphone, and a Microchip PIC16F684 Flash microcontroller. The receiver board integrates two Nordic nRF2460 audio streamer ICs, two AKM AK4430 24-bit stereo DACs, an AKM AK5374 24-bit stereo ADC, and a Microchip PIC16F684 Flash microcontroller. To enable easy connection to PC-based or analog audio systems both analog (RCA) and USB audio interfaces are included on the receiver board.
