SPMOD - MicArray


SPMOD_MicArray(Microphone array module) uses RY3708(DC-DC)Boost Module

SPMOD - MicArray Introduction

  • Using Sipeed-SPMOD interface(2.54mm * 8PIN ),unified MaixPy board interface
  • Transfer the SP-MOD interface to the FPC, and use the FPC to connect to the microphone array board
  • 3.3V to 5V boost regulator(DC-DC)(RY3708),easily drive microphone arrays.
  • Use the Grove interface to control the LED on the microphone array module.
  • It needs to be used with the SIPEED MICARRAY module.
  • Size:35.0*10.0*11.2mm
