The ANAVI Dev Mic is an open-source microphone designed to be compact, affordable, highly versatile, and to integrate machine learning into its design. It works in conjunction with the Seeed Studio XIAO RP2040 module and an omnidirectional digital microphone to deliver excellent sound capture and processing performance.

For artificial intelligence (AI) and machine learning (ML) speech applications, audio quality is critical, and the clarity of the microphone plays a key role. While affordable USB microphones may suffice for many applications, they often suffer from issues like excessive ambient noise, limited hardware flexibility, and proprietary firmware that cannot be updated or optimized.

Three Key Advantages of ANAVI Dev Mic:

Transparency: As open-source hardware, ANAVI Dev Mic promotes accessibility, learning, and the right to repair.
Extensibility: Featuring nine GPIO pins on the PCB, the ANAVI Dev Mic supports extensive hardware expansion, allowing you to add buttons, LEDs, sensors, and more to enhance its functionality for various use cases.
Customizability: Thanks to its open-source firmware, ANAVI Dev Mic can be tailored to meet your specific needs and preferences.

Fine-Tune Your Microphone

By flashing the firmware, you can personalize the ANAVI Dev Mic to suit specific applications or expand its functionality by connecting additional components, such as LED indicators, mute switches, and other buttons, through its I/O pins. Whether you’re conducting research, developing speech recognition systems, or creating interactive experiences, the ANAVI Dev Mic is a versatile tool to assist your projects.
