@yilinw010924

Hello! How are you? I can take your USB-C PD–powered USB 3 hub from concept to a production-ready design. I have solid experience with high-speed layouts, USB-PD hardware, and controlled-impedance routing for 5-10 Gbps signals. I will create a complete KiCad project including schematic, 4-layer (or higher) PCB layout with USB 3.0 SI rules, validated differential-pair routing, PD integration, EMI filtering, and full power-path protection. Both downstream ports—SuperSpeed via flex and USB2 for the RP2350—will follow proper return-path and length-matching requirements. Your suggested ICs (TUSB8042A, TPS25730, TPSM63606) are suitable, and I can base the design on TI’s reference material while optimizing for your form factor and long-cable EMI robustness. Deliverables: Gerbers, BOM with supplier links, pick-and-place, PD configuration, test-point plan, and bring-up support. I have shipped USB-PD and high-speed boards before and can provide references. Ready to begin immediately. Let’s build a reliable, production-grade hub. Best regards, YiLin W.

@OyebisiHakeeem

With my experience designing high-speed USB hardware and PD-powered embedded boards, I understand exactly what it takes to move this concept into a reliable, production-ready design. I will structure the schematic and PCB layout around your chosen devices TUSB8042A for the hub, TPS25730 for USB-PD, and a high-efficiency buck stage for the 5V rail—while ensuring full compliance with USB 3.x signal-integrity rules. This includes correct differential-pair impedance, length-matching, controlled return paths, and EMI-aware placement, especially since the upstream USB-C interface will run over a long cable. Both downstream ports will be implemented as specified: one SuperSpeed link to a camera via flex cable, and one USB 2 interface for the RP2350 board, each with integrated over-current and short-circuit protection. I will also include a clean auxiliary header for 20V/3A output, along with test points on all critical nets for validation. Once complete, you will receive the full manufacturing package: Gerbers, pick-and-place files, a complete BOM with distributor links, and any firmware/config files needed for the TPS25730 and hub controller. I’ve shipped USB-PD and high-speed boards before, and I am confident I can hand you a prototype-ready design that passes your DRC/ERC review and is straightforward to bring up in the lab.

@Georgeoustar

Hi there? I can take your USB-C PD compact hub from concept to a production-ready KiCad design, including schematic, controlled-impedance PCB layout, and full manufacturing outputs (Gerbers, PnP, BOM with sourcing). Your proposed IC set (TUSB8042A hub, TPS25730 for PD, TPSM63606 for 20V→5V) is a solid starting point; I’ll refine the power tree, add per-port protection, and ensure SuperSpeed routing (differential pairs, reference planes, return paths, ESD/EMI filtering) meets USB 3.x guidelines. I’ll also include test points for PD negotiation, hub status, and high-speed lines where practical so bring-up and SI validation on the bench are straightforward. Once the first prototypes are built, I’m happy to support basic bring-up and any small ECOs needed to get you to a stable rev.

@raghavg42

I can take this project from concept to a clean, production-ready Altium design without any hand-holding. The board will have a solid USB-C PD front end, a high-speed USB-3 SuperSpeed port routed to a flex connector for your camera, a USB-2 Type-A port for the RP2350 board, proper over-current protection on every rail, and a stable 20V→5V power stage. I’ll make sure the layout actually respects real-world SI and EMI rules so the hub behaves properly even with a long upstream cable. You’ll receive the full Altium project, fabrication-ready Gerbers, assembly files, and a complete BOM with alternates. I’ve built multiple PCBs featuring USB-PD, USB3 high-speed differential routing, and compact power stages, so I’m comfortable handling the details that make these boards reliable. Once you’re ready for prototypes, I can also support bring-up to make sure everything enumerates, negotiates, and powers up exactly as expected.

Deliverables will include KiCad schematics, impedance-controlled PCB layout (Gerbers, pick & place, stack-up notes), complete BOM with supplier links, and PD configuration files. All rails will have protection and power sequencing validated. I’ll include test points, return-path optimization, and 20 V → 5 V buck design for clean downstream power. Having shipped multiple USB-PD and SuperSpeed boards, I can support prototype bring-up and validation immediately after design delivery.
