Configurable digital microphone board

8CH-DMIC

Overview

8CH-DMIC is a highly configurable digital microphone board that complements the NXP MCU product range including PDM microphone interfaces. The board comes with 11 digital PDM microphones, up to 8 can be active simultaneously, and can be configured with many different microphone topologies for evaluation and development. The 8CH-DMIC connects to the host MCU evaluation board via a simple connector, which also provides power and optional drive signals to drive the on-board LEDs. All design files are provided for this board, and example code is also provided in the MCUXpresso SDK for the host MCU evaluation board.
