We do need a small PCB with 4x MEMS Microphones, like the MP34DT01 from STMicro.
Job consist of routing the PCB, creating the layout with small suitable MCU providing an USB interface for sound stream.
Experience requested in AUDIO to create the design and measurement for the suitable gasket (!) for best sound behind a steel wall of a kiosk system. Optional Alexa AVS integration.
3D design for production for proper assembly of the microphone board behind a steel wall.
Hello Interesting project. I have worked on a similar project. With I2S MEMS mics and arduino. Happy to design the circuit. Do the Pcb layout and assist in testing if needed. Thanks.
