About this Gig
Need a custom PCB for an AI voice recorder, smart audio device, or embedded voice capture system?
I will design a tailored ESP32 S3 voice recorder PCB with a three microphone array interface and eMMC storage architecture to support your hardware requirements.
What I can design:
I2S or other suitable digital microphone interfaces, depending on your selected components
eMMC storage interface and supporting circuitry
USB connectivity, power management, charging, and protection where required
Schematic capture, PCB routing, component selection, and design checks
Gerber, BOM, and manufacturing files for JLCPCB or PCBWay
Why work with me?
I focus on organized schematics, practical component selection, manufacturable PCB layouts, and designs tailored to your project's requirements. I will consider audio interface routing, power stability, component placement, and storage connectivity during the design process.
Please message me before placing an order to discuss your microphone type, storage capacity, board dimensions, power source, and required deliverables.

FAQ
Can you design a custom ESP32-S3 AI voice recorder PCB?
Yes, I can design a custom PCB around the ESP32-S3 based on your recording, connectivity, power, and storage requirements.
Can you integrate three microphones into one PCB?
Yes. I can design the microphone interfaces and supporting circuitry after confirming whether you need digital or analog microphones and how the audio channels should operate.
Can you add eMMC storage to the design?
Yes. I can design the eMMC interface, power connections, and supporting components for a compatible storage device, subject to ESP32-S3 interface and system requirements.
Does the package include AI transcription or voice recognition?
PCB design alone does not include AI software. Firmware, audio processing, transcription, and cloud integration can be discussed as separate requirements.
Will I receive files for JLCPCB or PCBWay?
Yes. The applicable package can include Gerber files, a bill of materials, and other manufacturing outputs required by your selected fabricator.
Can you design a compact, battery-powered recorder?
Yes. Share your size limits, battery type, expected runtime, and charging requirements so the power architecture can be planned appropriately.
Can you modify an existing voice recorder schematic or PCB?
Yes. Send your existing design files and explain the changes you need so I can assess the scope before you order.
