Each circular microphone array board integrates:
- 16x high-SNR MEMS microphones, positioned for uniform spatial coverage.
- 2x Texas Instruments audio codecs – each codec supports up to 8 microphone channels.
- 1x TI Serializer (DS90UA101) – aggregates multi-channel I²S streams into a single high-speed differential link.
- Automotive Rosenberger RF connector – ensures a shielded, mechanically robust interface to the receiver board.
