Mico uses Raspberry Pi Pico IC
Author: EIS Release Date: Jan 10, 2022
Maker Mahesh Venkitachalam has designed a high quality microphone he calls Mico using the main component of the Raspberry Pi Pico – the RP2040 controller chip – which can be bought separately from the Pico platform.
The sensing device is a MEMS microphone that outputs a pulse density modulated (PDM) signal.
Mahesh designed a PCB that holds the RP2040 with the MEMS microphone and a USB connector.
It comes with full schematics and source code available on its GitHub page.
