16-MEMS Microphone Array: Production-Ready Experimental Design

16-MEMS USB Microphone Array

🚧 Project Transition Notice

The 16-MEMS USB Microphone Array is now part of larger GEEK VAULT project hosted on usbser.com.

🎁 Existing Buyer Entitlement

All previous purchasers are automatically entitled to Supporter Edition ($199 value) access on the new GEEK VAULT platform.

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

Better Than Crowdfunding

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 β€” an ongoing research project that works as a standard USB microphone today. The core design is complete and ready to be ordered as a fully-assembled PCB from JLCPCB.com, requiring no technical or soldering skills.

Skip the Wait, Own the Tech

Why gamble on a crowdfunding campaign? For approximately $130, you can order the PCBs and get two physical microphones in hand, with no delays or unfulfilled promises.

Follow the Journey

The hardware platform was designed from the start to be flexible and capable enough to support ongoing experimentation β€” which means more interesting content for you! Follow my YouTube channel for the latest updates on feature development, including beamforming, voice effects, and tap-to-mute using impact sensing.

Core Hardware Features

βœ“ Accurate timing with an RX8025T RTC
βœ“ Motion-controlled effects using LSM6DSRTR IMU
βœ“ Standalone/backup recording to a microSD card

Project Files Included

All project files are available through the GEEK VAULT platform:

βœ“ EasyEDA Pro schematics & PCB project
βœ“ STM32CubeIDE firmware source
βœ“ PCB fabrication files, ready for manufacturing
βœ“ Pre-compiled firmware binaries
βœ“ Design notes & explanations

Basic, usable firmware with flashing instructions is available! Updated video on performance will be posted on my YouTube channel.

How to Get Your Microphone

You can expect to spend about $130 in total to make two boards using third-party manufacturing services like JLCPCB.com. That comes out to roughly $65 per board.

Basic functionality verified. RTC, SD-Card slot, accelerometer, and headphone codec not yet tested. Everything else appears functional, but if these features are critical for you, please wait for the next revision. Known issue: green LEDs are slightly brighter than red onesβ€”will be adjusted in the next revision.

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