Smart Home Wearable Audio and IoT PCB Engineer
I design connected electronics and production ready PCB hardware for smart home devices wearables audio products access systems appliances and IoT products. My work covers Matter Thread ESP32 C6 ESP32...
About this Gig
I design audio PCB hardware for smart speakers, voice assistants, intercoms, wearables, USB audio devices and embedded products.
I can develop MEMS microphone arrays, audio DSP, codecs, ADC/DAC, I2S/TDM, USB audio, speaker, headphone and amplifier interfaces, with low-noise analog and mixed-signal PCB layout. I also handle MCU/DSP integration, power management, grounding, decoupling and signal-path planning.
My focus is more than component placement. I structure the audio signal chain and PCB layout to reduce digital noise, ground coupling, EMI and interference between sensitive analog audio and high-speed digital circuitry.
Deliverables can include schematic design, PCB layout, component selection, BOM, Gerbers, source files, 3D PCB and manufacturing-ready documentation.
Ideal for MEMS microphone boards, beamforming hardware, voice detection devices, smart speakers, audio interfaces, DSP audio systems and embedded audio products.
Please send your block diagram, channel count, microphone/codec/DSP preference, power source, PCB size and connectivity. I can review the architecture and recommend a solution.
FAQ
Can you design a MEMS microphone array PCB?
Yes. I can design MEMS microphone interfaces and multi-microphone PCB layouts for voice detection, beamforming, smart speakers, wearables and embedded audio systems.
