About this Gig
Hello and Welcome!
Modern AI voice products fail when audio quality, power optimization, and PCB integration are not engineered correctly from the hardware level. Poor microphone routing, unstable power rails, RF interference, storage bottlenecks, and inefficient firmware architecture can completely reduce the performance of an AI audio system.
Whether you are building a wearable recorder, smart assistant, surveillance device, meeting recorder, or IoT audio product, I will develop a reliable and manufacturing-ready solution tailored to your requirements.
What I Will Provide:
- Complete schematic design
- Professional PCB layout and routing
- ESP32-S3 integration
- 3 microphone array implementation
- eMMC storage interface design
- Power management circuit
Why Choose Me:
Strong experience in embedded hardware and IoT PCB systems
Deep understanding of audio signal integrity and RF design
Optimized designs for manufacturability and reliability
Clean and organized PCB layouts with professional standards
Ready to turn your AI audio idea into a reliable production-ready device? Message today and lets build a professional ESP32-S3 AI voice recorder PCB for your product!!!!
