Sipeed 6+1 Microphone Array is a 6-microphone expansion board for MAIX AI development boards designed for AI and voice applications. The included 6+1 digital microphones and 12 three-color LEDs allow it to support sound localization, beam forming, speech recognition, etc. With the 6+1 microphone array and MAIX development boards, applications like AI speaker can be prototyped easier and faster. Prototypes of a sound source tracking camera can also be built rapidly if a Pan-Tilt camera is added.
