I will design electret mems microphone array pcb i2s pdm adc esp32 audio interface pcb
About this Gig
Need a custom electret or MEMS microphone array PCB for your audio, voice or acoustic sensing project?
I will design a custom microphone array circuit and PCB tailored to your application, from schematic development to manufacturing ready files.
My services include:
- Electret and analog MEMS microphone circuits
- Digital MEMS microphones with I2S or PDM interfaces
- Multi-channel audio acquisition and ADC integration
- Low-noise preamplifiers, biasing, filtering, and power management
- Microphone placement and PCB layout for acoustic performance
- ESP32, STM32, USB audio, and embedded-system interfaces
- BOM, Gerber, schematic, and manufacturing documentation
Applications: smart speakers, voice assistants, beamforming systems, conference microphones, acoustic monitoring, sound detection, robotics, and IoT devices.
I focus on practical circuit design, careful component selection, signal integrity, and manufacturable PCB layouts.
Please message me before ordering so we can confirm your microphone type, channel count, interface, board dimensions, and project requirements.
Let's turn your audio hardware concept into a custom PCB design.
FAQ
Can you design both electret and MEMS microphone arrays?
Yes. I can design analog electret circuits, analog MEMS interfaces, and digital MEMS microphone arrays.
Can you design a multi-channel microphone PCB?
Yes. I can develop multi-channel designs, with the channel count and layout confirmed according to your requirements.
Do you support I2S and PDM microphones?
Yes. I can integrate compatible digital microphones and their clock, data, power, and processor interfaces.
Can you design a low-noise microphone preamplifier?
Yes. I can work on microphone biasing, gain stages, filtering, grounding, decoupling, and noise-conscious layout.
Can the PCB support beamforming?
I can design the microphone hardware and interfaces needed for beamforming. The algorithm, timing synchronization, and processing firmware may require a separate scope.
Will I receive manufacturing files?
The Standard and Premium packages include the listed PCB manufacturing files and documentation. Basic includes schematic-focused deliverables.
Can you guarantee audio quality or noise performance?
I can design toward agreed electrical targets, but actual performance depends on microphone selection, enclosure acoustics, layout, power supply, and validation testing.
