Two-microphone wireless audio reference design kit
October 24, 2011 // Julien Happich
The nRFready Microphone wireless reference design kit provides a complete, fast-track two-microphone audio streaming solution ideally suited to consumer gaming and home karaoke applications. Developed jointly by AKM Semiconductor and Nordic Semiconductor, the nRFready Microphone kit employs Nordic's newly launched nRF2460 2.4GHz mono audio streamer IC and audio converters from AKM to deliver 16-bit uncompressed PCM audio quality, less than 22ms latency, and over 100-hours of battery lifetime (per mic) from two AA batteries.
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.
