I’m a Senior Hardware Design Engineer with 5+ years of experience in schematic design and compact PCB layout. I can design an 80 mm × 15 mm linear PCB integrating a USB 2.0 hub, a USB audio codec, and a dual-channel Class-D amplifier, while maintaining a low-profile layout suitable for a glasses temple arm. I will deliver a complete schematic, optimized PCB layout, impedance-controlled routing where required, and full manufacturing files (Gerbers, BOM, pick-and-place, and assembly drawings) ready for prototype and production. Looking forward to reviewing your requirement document and starting the design. Note: Bid price does not include components procurement, PCB manufacturing, and Assembly.

With my skills in Electronics, Microcontroller, and PCB Design and Layout, combined with my broad engineering background, I'm confident that I can bring significant value to your Slim USB Hub Audio PCB project. My multi-disciplinary understanding allows me to approach design challenges holistically, mindful of both electrical and mechanical constraints, like the unique space inside your glasses prototype's temple arm. Throughout my 5-year Electrical & Electronics Engineering degree at ATBU Bauchi, I honed my deep knowledge of electronic circuits, digital systems, communication systems. These principles are key to successful PCB design. I am proficient in using KiCad and EasyEDA pro, solid skills that would be vital for this project. I'd love to leverage this role to showcase my immaculate attention to detail in schematic capture, PCB layout, impedance-controlled routing where necessary and delivering comprehensive manufacturing packages. And if necessary, I can also conduct a small run of prototypes for you. All said, I can assure you that with me on board your prodution-ready design will be

I reviewed your project and I can design the long, narrow PCB (80 mm × 15 mm) that integrates the USB 2.0 hub, USB audio codec and dual-channel Class-D amplifier into a single board suitable for your glasses prototype. I will keep the layout linear and low-profile so it can fit comfortably inside the temple arm. I have experience with USB-based audio and compact PCB layouts, so I will ensure clean power routing from the 5V USB rail, stable microphone input and noise-free stereo output without hiss or idle amplifier noise. Proper grounding and signal separation will be used to maintain reliable performance in the tight space. Deliverables will include: • Complete schematic and PCB design • Gerber and drill files for manufacturing • BOM with available part numbers and footprints • Pick-and-place and assembly drawings The design will be fully production-ready and I can also support prototype manufacturing.

Hello, I reviewed the project details and understand the goal of integrating the USB 2.0 hub, USB audio codec (mic + stereo out), and dual-channel Class-D amplifier into a single linear PCB (~80 mm × 15 mm) that fits inside the temple arm of your glasses prototype. I can design a compact, low-profile board that runs directly from the 5 V USB rail while maintaining clean audio output and reliable microphone input for voice prompts and media playback. My approach will include schematic capture, component selection with currently available parts, and a linear PCB layout optimized for the narrow mechanical envelope. I will handle controlled routing for USB differential pairs, careful grounding and filtering to avoid noise from the Class-D stage, and placement strategies to minimize height and interference. The final deliverables will include production-ready Gerber files, BOM with sourcing references, pick-and-place files, and assembly drawings. I can also assist with prototype fabrication and testing support if needed.
