@TopRated209

Hi! Thank you fro inviting me to this project. I checked the project where schematic is completed but PCB is yet to be completed. I went through the schematic as i have worked quite alot with esp 32 and i have found one issue with your USB connection. The direct USB connections to esp 32 is not swapped, they are differential and must be connected like D+ to D+ and D- to D-. I can check each and every component against the datasheet in details for correct operation as well as route the components on PCB. Thanks Regards

@yaroslavmark

Hi, this type of pre-production KiCad review is exactly the kind of work I regularly handle before boards go to JLCPCB assembly, especially compact USB-C power and embedded-control designs where a small oversight can become an expensive fabrication issue. I have 10+ years of PCB design and DFM experience and completed 120+ production-ready board reviews involving USB power routing, load-switch circuits, thermal validation, JLCPCB assembly optimization, and footprint/BOM verification. Approach ✅ I will perform a full schematic and PCB audit covering footprint-to-part validation, USB-C 5V/3A routing integrity, TPS22965 implementation, thermal considerations, grounding, copper width, and assembly constraints for JLCPCB. ✅ I will verify every BOM item against JLCPCB Basic/Standard library availability, identify any hidden extended parts, and recommend compatible substitutions where cost or availability can be improved. ✅ I will provide annotated markups directly on the KiCad design files, along with a concise PDF report describing each issue, its impact, and the exact corrective action required before fabrication. Questions ✅ Are both USB-C channels intended for pure 5V passthrough only, or is any USB data/CC negotiation functionality also expected? ✅ Which copper weight and board stack-up are planned for handling the sustained 3A current paths? Best, Yaroslav

@hamzazayyad

Dear Sir, I have strong experience in KiCad PCB review, power electronics, USB power-path design, and JLCPCB manufacturing optimization. I can fully review your KiCad 10 project before fabrication and verify the design from both the electrical and production sides to minimize risk before assembly. Your project is well within my expertise, especially: • USB-C 5V/3A routing and protection • Load switch circuits using TPS22965DSGR • JLCPCB/LCSC “Basic vs Extended” BOM optimization • Footprint-to-part verification and assembly checks • PCB manufacturability and reliability review I will carefully inspect: • Footprint accuracy versus selected LCSC/JLCPCB parts • USB-C connector pin mapping and CC handling • Trace widths, thermal reliefs, grounding, and power routing • Possible SI/current-handling issues for 3A paths • Placement/orientation mistakes and assembly risks • Whether all selected parts are truly in the Basic library where possible • Any missing protections, pull resistors, or layout improvements Deliverables: 1. Professional PDF review report with issues, risks, and fixes 2. PCB/schematic markups showing exact problem locations 3. Updated BOM with recommended “Basic” substitutions if needed I understand this board will go directly to fabrication without prototype validation, so I will review it with production-level attention to detail, not just a quick visual inspection. Best regards, Hamza Electronics Engineer

@TingWang250617

Hi, Thank you for your invitation. Yes, this is absolutely within my scope. I can perform a full pre-fabrication review of the KiCad 10 project before you send it to JLCPCB, including: - Schematic review - PCB layout review - Footprint-to-part verification - JLCPCB Basic vs Extended library validation - BOM sanity check - Power-path and USB-C routing review - TPS22965 implementation verification - Thermal and current-handling review for the 5V/3A channels - DRC/ERC and manufacturability checks I’ll also verify that: - all footprints match the intended manufacturer part numbers, - no unintended Extended parts slipped into the BOM, - assembly-friendly footprints/orientations are used, - trace widths, vias, copper clearances, and connector layouts are appropriate for the intended current, - and there are no obvious issues that could cause fabrication or bring-up problems. For deliverables, I will provide: - A concise PDF report listing issues, risks, and recommended fixes. - Markups/screenshots showing exact schematic or PCB problem locations. - An updated BOM if substitutions to JLCPCB Basic parts are recommended. Best regards, Ting

@tetianam8

⭐⭐⭐⭐⭐ Your project is exactly the kind where a proper design review can save a very expensive “first board lesson.” Since you’re going straight to fabrication and assembly without an intermediate prototype stage, the important part is verifying manufacturability, footprint correctness, JLCPCB library compatibility, USB-C power-path behavior, thermal considerations, and potential assembly/routing issues before release. I’m very comfortable reviewing KiCad projects intended for JLCPCB production, including BOM validation against Basic/Standard parts, footprint verification, power routing analysis, and practical DFM checks. I can go through both the schematic and layout carefully rather than just running automated checks. I will review: • TPS22965DSGR implementation and load-switch routing • USB-C 5V/3A trace widths and connector pin mapping • Footprint-to-part-number consistency • JLCPCB Basic vs Extended library usage • Thermal sensor integration and placement • Grounding, return paths, and copper balancing • Assembly risks, polarity issues, and manufacturability concerns A few quick questions: Target copper weight (1oz or higher)? Any ESD protection already implemented on USB-C lines? Are both USB-C channels independently switchable under load? I’d be happy to review the KiCad package and give you a fabrication-confidence assessment before you place the JLC order.

@shivkantverma

Hi, Greetings.! I am interested to work on your project. i can verify your design files as per your requirment. Looking forward to work with you. Thank you shivkant

@electronicsdone

Dear Client, The biggest risk in this project is not creating the schematic or routing the PCB. It is sending the design to fabrication with unnoticed footprint mismatches, incorrect JLCPCB part mappings, weak USB-C implementation details, or layout issues that only appear after assembly. That is where a detailed pre-manufacturing review becomes critical. I can help you fully validate your KiCad 10 schematic and PCB layout before fabrication so you can move to JLCPCB with confidence instead of risking costly board revisions. I would approach this by: 1. reviewing the complete KiCad project, including schematic, PCB layout, footprints, BOM, and JLCPCB part mappings to identify footprint mismatches, incorrect symbols, assembly risks, and non-basic components 2. checking the USB-C 5V/3A passthrough implementation, TPS22965DSGR switching layout, thermal considerations, trace sizing, grounding, and signal integrity to catch issues before manufacturing One key question: Do you want only review/commenting, or should I directly apply all approved corrections inside the KiCad project files as well? Message me and I’ll help ensure the design is truly fabrication-ready before you commit to assembly and production. Best regards, Prat PCB Must Innovations
