I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. All electrical, mechanical and interface details are spelled out in the attached requirement document. Once you’ve reviewed it, I’d like you to take the project through schematic capture, PCB layout, impedance-controlled routing where needed, and produce the full manufacturing package (Gerbers, BOM with part numbers in current supply, pick-and-place, and assembly drawings). A small run of prototypes would be a plus, but the primary deliverable is the complete, production-ready design.

Dear Sir/Madam, I would be glad to assist in converting your prototype modules into a compact custom PCB suitable for integration inside the glasses temple arm. I have strong experience in embedded hardware design, compact PCB layouts, and integrating USB, audio codecs, and amplifier circuits into space-constrained products. Designing a board within an 80 mm × 15 mm linear form factor requires careful component placement, power distribution, and signal routing to maintain low noise and reliable operation. I can review your requirement document and develop a clean schematic and optimized PCB layout that fits the narrow mechanical constraints while maintaining proper USB signal integrity and stable audio performance. In previous projects, I have designed compact embedded PCBs for signal acquisition systems, sensor hubs, and communication modules where tight mechanical constraints and low-noise analog routing were critical. For this project I will deliver: • Complete schematic design integrating the USB hub, audio codec, and Class-D amplifier • Compact PCB layout optimized for the 80 × 15 mm linear form factor • Proper USB routing and audio signal layout to minimize noise and interference • Manufacturing package including Gerbers, BOM with available components, pick-and-place files, and assembly drawings If required, I can also support prototype manufacturing and bring-up guidance. Best regards, Chandan Dutta
