Mico: Open source, high-quality PDM to USB microphone based on Raspberry Pi RP2040 chip

Mico is a high-quality PDM to USB audio microphone based on the Raspberry Pi RP2040 chip. Most compact microphones available for embedded Linux systems such as the Raspberry Pi have high noise and low sensitivity. By pairing a high-quality PDM microphone with a standard USB audio output, Mico gives you an audio input platform that you can tailor to your needs. Mico is a great platform to learn and experiment with the RP2040 and digital audio. It can be used as a universal USB microphone for a Raspberry Pi, desktop or laptop computer. Mico can also be used as a high-quality USB audio input for embedded machine learning applications. Additionally, because TinyML supports RP2040, Mico can be used as a standalone edge computing audio device.
