Hello, this is Bojan. Thanks for sharing the project. I want to be upfront: although I work in software development, backend systems, automation, and embedded engineering, I don’t take on full custom PCB designs for audio devices that require full signal‑integrity planning, multilayer layout, low‑noise routing, codec/amplifier integration, and production‑ready Gerbers. This work needs a specialist focused on audio‑grade PCB design, impedance control, filtering, shielding, and IPC‑compliant fabrication files — skills outside my current scope. Since you need a complete schematic, multilayer layout, BOM, design notes, and 3D fit verification, a specialist in audio hardware + PCB layout will serve you much better. I don’t want to take on a role that depends heavily on analog‑signal cleanliness and audio‑specific board engineering. If you ever need help with technical workflow planning or automation strategy, I can assist — but I’m not the right fit for this PCB design project.

@antoniod83

I have solid experience in PCB design, power supply, and signal integrity, which would be very helpful for your audio project. I’d be happy to discuss the project with you and understand the requirements better.

@thanhphuong14

Hello, I’m a PCB design engineer with several years of experience in electronic hardware and PCB development. I have worked on audio-related projects, including a high-power amplifier power-supply PCB using dual ±V rails, CRC filtering, star-grounding, and UPC1237 speaker protection. This project required careful attention to grounding, high-current routing, power integrity, and noise reduction. I also have experience with multilayer PCB design, power regulation, signal integrity, DFM, and preparing complete manufacturing files such as Gerber, BOM, Pick-and-Place, and 3D STEP. I believe my practical experience in audio, power, and production-ready PCB design is well suited to your project.

@roheel637

Hi, Please send me your project requirements and block diagram you have. I'm willing to do this project. Thanks

@morne01

?IF YOU'RE NOT HAPPY, YOU DON'T PAY.? Recently, I helped a client design a PCB for a similar audio device, focusing on low noise and efficient power management. I can assist in creating a complete PCB that meets your high-quality audio playback requirements while ensuring reliability and compactness. Your project emphasizes a clean, professional layout with optimized ground-plane management for the best audio paths, which I fully understand. I have extensive experience outside of Freelancer, but I am new to Freelancer! My expertise includes schematic capture, multilayer board layout, and producing detailed BOMs, all while following IPC guidelines for production readiness. Regards, MORNE.

@malindu0027

Hello, I will turn your block diagram into low-noise and low-power PCB that is production ready. I will also provide 3D models of PCB assembly and enclosure. Let's discuss details and start right away. Thanks.

@rehmanafridi776

Hi, I can design your compact, low-noise audio PCB from scratch using EasyEDA, fully compliant with IPC manufacturing standards and optimized for your enclosure. As an electrical engineer, I also leverage MATLAB Simulink for power and signal integrity analysis to ensure pristine audio performance before final routing. High-fidelity consumer audio demands rigorous mixed-signal layout practices. I will implement the following: Low-Noise Ground Management: Strict partitioning of analog and digital ground regions (AGND/DGND) tied at a single star point to eliminate digital return currents from corrupting audio paths. Clean Power Rail Decoupling: Localized filtering and low-ESR bypass capacitors placed immediately at the codec and amplifier power pins to suppress switching transients. Complete Fabrication Package: Delivery of native EasyEDA source files, a full Gerber X2 set, drill files, IPC-compliant centroid files, and a 3D STEP model for mechanical validation against your enclosure. Sourcing-Ready BOM: Formatted with current, in-stock component part numbers and verified alternates to prevent supply-chain snags. Design Notes: Documentation on impedance control, filtering decisions, and shielding techniques used in the layout. I am ready to review your block diagram, enclosure dimensions, and codec datasheets right away to begin the schematic capture.

@Kulkarnipushkar

Hello, I can help with the complete PCB design workflow for your audio device, from schematic capture through manufacturing files. I have hands-on experience with KiCad schematic design, component selection, PCB placement, routing, ERC/DRC checking, and Gerber generation. I can work from your block diagram and amplifier/codecs datasheets to create a clean schematic, select suitable footprints and components, and develop a compact PCB layout with careful grounding, power routing, decoupling, and separation of sensitive audio signals. I will provide organized KiCad source files, BOM with component alternatives, Gerber and drill files, along with design notes and a 3D STEP model where applicable. I will also keep the design organized so future revisions are easy. I am particularly interested in building this project because it combines PCB design, embedded electronics, and signal integrity. I can begin by reviewing your block diagram and datasheets and then proceed systematically from schematic to production-ready PCB.
