The Sipeed 6+1 Mic Array Module is designed with 7 high-sensitivity digital microphones MSM261S4030H0 that support the I2S communication protocol, with an integrated 24-bit signal preprocessor. The microphones are arranged in 6 different directions, plus 1 central microphone, and 12 RGB LEDs are also included. This allows you to perform professional AI audio recognition applications, such as sound source localization, beamforming, speech recognition, etc. The module is supported by sample code on the Sipeed RISC-V Maix, FPGA Tang, and Linux Lichee product series.
