Hi, I can design a compact XMOS-based MEMS microphone array PCB with real-time beamforming, AEC, and noise suppression, delivering clean audio through simple header pins ready for your downstream hardware. MY APPROACH I will design the MEMS analog front-end, selecting low-noise capsules with optimized biasing and matched impedance for 2–4 channel array geometry. I will capture the full schematic and layout a minimal PCB, prioritizing compact footprint, clean analog routing, and XMOS power integrity. I will develop the XMOS firmware using xCORE DSP libraries, implementing beamforming, AEC, and noise suppression with tunable parameters. I will configure the audio output headers, ensuring clean, low-latency PCM delivery with clear pin mapping for easy downstream integration. I will prepare all production and build artifacts, including Gerbers, BOM with in-stock supplier PNs, firmware build scripts, and tuning utilities. DELIVERABLES Hardware Package: Annotated schematic, compact PCB layout, Gerbers, and Pick & Place files. Production BOM: In-stock supplier part numbers with lifecycle status. XMOS Firmware: Tested AEC, NS, and beamforming code with full build instructions. Quick-Start Guide: Header pin mapping and audio capture walkthrough. TO START What is your target array geometry (linear, circular) and mic spacing? What sample rate and bit depth does your downstream hardware expect? Any preferred MEMS capsule brands or existing parts to design around?

With my extensive background in software development, web and mobile app development, as well as experience in Electronic circuit designing and integrating IoT devices, I believe I am the right fit for this project. I am particularly skilled in utilizing latest technology like A.I., Machine Learning and IoT, which greatly informed my fluency with Hardware Description Languages (HDLs) such as VHDL and Verilog, further confirmed by my proficiency with FPGA board programming. In addition to my software and hardware skills, I am also adept at working with compact dimensions. I understand that the smaller the PCB, the better for your project so not only can I design a compact-sized 2-4 channel analog MEMS microphone array around an XMOS processor effectively for you, but can also utilize the free tools from XMOS to write firmware that would compile and run seamlessly. My core aim is to ensure you have everything you need to get your project off the ground hassle-free and that resonates strongly with your brief. I will ensure delivery of production-ready Gerbers, annotated schematic, BOM with supplier part numbers in stock today, tested XMOS firmware plus a quick start guide showing header-pin mapping & how to fetch audio. Together with my team

Greetings Dear Hiring Manager I have read the description of your project and I understand everything. I am an expert in XMOS xcore-200 architectures and high-density audio PCB design, with extensive experience in implementing real-time DSP pipelines for MEMS microphone arrays, including beamforming, AEC, and noise suppression. I specialize in ultra-compact layouts that integrate analog-to-digital conversion and XMOS signal processing libraries, ensuring a production-ready hardware-firmware package that delivers low-latency, high-fidelity audio directly to your downstream headers. I am waiting on chat to discuss more and I am willing to start it now. Best Regards, Zain Abbas

Hi, I hope you are doing well. I’m Muhammad Tanzeel Ehsan, an Electronics Engineer currently working as a Signal and Power Integrity Engineer with strong experience in multilayer PCB design, embedded systems, and mixed-signal hardware using KiCad, Cadence Allegro, and Altium Designer. I can help design the compact MEMS microphone array board including schematic capture, PCB layout, component selection, and a production-ready BOM. I have experience designing high-speed and mixed-signal boards, ensuring proper signal integrity, power distribution, and low-noise analog routing, which is critical for microphone arrays and DSP-based audio processing systems. I will ensure a compact PCB layout with proper grounding, shielding, and microphone placement suitable for beamforming applications. For the deliverables, I will provide the schematic, PCB layout, Gerber files, pick-and-place, and a ready-to-order BOM, along with clear documentation for header pin mapping and board bring-up. I am quoting for the hardware design and production files, ensuring the board is clean, manufacturable, and ready for integration with your XMOS DSP workflow. I would be happy to discuss the microphone configuration and board constraints so we can build a reliable and compact solution.

Hi, there. Timeline : 3 Days, Budget: 23000INR I am interested your project. Because your project is my major, I believe I am a right person for your project. I have experience designing compact embedded audio hardware and DSP systems, including microphone arrays and real-time audio processing pipelines. I can develop a small 2–4 channel analog MEMS microphone array PCB around an XMOS processor, handling schematic design, optimized PCB layout, and careful component selection to keep the board compact and production-ready. I will also implement XMOS firmware with beamforming, acoustic echo cancellation (AEC), and noise suppression, ensuring it builds and runs using the official XMOS free toolchain. The hardware will expose clean audio output via simple header pins, making integration with downstream hardware straightforward. Along with the design files, I will provide Gerbers, pick-and-place data, a BOM with currently available components, tested firmware, and a quick-start guide explaining pin mapping and audio retrieval. I hope to hear from you. Thank you.
