Invensense's ICS-52000 is a bottom port microphone with a TDM digital output. This demo board contains 16 ICS-52000 microphones in a 4 x 4 array with 15 mm spacing. All microphones are synchronously sampled together when connected together on a common TDM bus. The board can be set up for arrays of 4, 8, 12, or 16 microphones.
