16-MEMS USB Microphone Array for Creators & Makers

16-MEMS USB Microphone Array

A professional-grade USB microphone and audio platform designed to give creators and makers freedom that big brands rarely offer.

Why This Microphone?

I wanted a microphone that wasn’t just another black cylinder stuffed with budget parts. I dreamed of a massive microphone array packed with features. At first, the idea seemed impossible. But I asked: What if I can pull this off?

The result is this 16-MEMS microphone array: a USB mic built to grow with you. Ongoing firmware updates add beamforming, tap-to-mute, custom effects, and more — so the mic you get today keeps getting smarter — perfect for podcasts, streaming, or experiments.

Built for Serious Creators — and Curious Engineers

Designed for clarity, flexibility, and experimentation:

High-quality sound from a 16-MEMS microphone array
Real-time processing with an STM32H7B0 MCU
Accurate timing with an RX8025T RTC
Motion-controlled effects using LSM6DSRTR IMU
Standalone/backup recording to a microSD card

The PCB has enough headroom for years of firmware growth.

Your purchase gives you complete design files and lifetime updates. To turn those files into a working microphone, you’ll need to order a PCB from JLCPCB.com. A short video and PDF walk you through the PCB order step by step. Expect to spend about $100 to make two boards (minimum order), depending on color, shipping, and options. That adds up to roughly $65 per microphone.

Do not order PCBs yet. I am completing a final review to prevent any hardware issues. I'll announce here when the design is verified for production. Please be sure to download the latest file archive before manufacturing. To avoid confusion, the complete manufacturing guide will be released once the review is complete, but no later than October 25, 2025.

Note: I'm not affiliated with JLCPCB. This is only an estimate - final cost depends on current component prices and your chosen manufacturer.

Support & Legal

I design, test, and support this project myself — email me anytime: support@georgymoshkin.com

The PCB files are production-ready, and I place test orders to ensure everything works smoothly. You may adjust cosmetic options like solder-mask color when uploading to JLCPCB.com, and keep the default layer count and board thickness.

This is a single-engineer experimental product that’s constantly improving. While there may be occasional hiccups, I provide full transparency so you know exactly what you’re buying.
