Hi I am an embedded systems engineer with over 16 years of experience designing production PCB hardware for compact IoT and consumer devices. I can design this board around your existing STEP enclosure so the ESP32 headers, TFT FPC, USB-C charging port, buttons, battery connector, sensor connector and mounting points all line up correctly instead of being treated as an afterthought. My approach would be to first confirm the mechanical constraints from the enclosure and display/sensor drawings, then create the schematic, select commonly available charger, regulator and protection parts, place the critical mechanical items, and finish with routed PCB, DRC checks and manufacturing outputs. I can also suggest reliability or assembly improvements, such as power protection, connector orientation, test points and clearance changes, before locking the design. I have worked on ESP32-based products with LiPo charging, USB-C power input, small TFT displays and enclosure-driven PCB layouts. Some prior commercial designs cannot be shared publicly, but I can show relevant examples privately. A few details I would confirm are the exact ESP32 dev board model, soil sensor connector type, charging current target, and whether you want the board in KiCad, Altium or Eagle. Please contact me to discuss details.

As you are supplying the STEP file of the enclosure it becomes quite easy to get the electronics perfectly fitted inside, and I will design the board with all 3D models so collaborating with MCAD is straightforward to see exactly where the display and connectors fit inside the enclosure before moving to final PCB design. This is an easy job but when you need the design to be perfect a lot of work hours are involved, hence the project fee is what it is, though I would suggest using an ESP32 module instead of a breakout board for a neat and tidy finish as well as reliability because you can then order the fully populated board directly to your doorstep and I will add a programming port so you can program the ESP32 conveniently. I will also design the schematic with low power operation in mind to maximise battery throughput, and I will design the product and generate all the manufacturing files needed for PCB production and assembly. I have designed many complex boards to fit inside tight spaces and mechanical constraints so you can rest assured your design will come out nicely and with a professional touch

Hi, I can help design or revise your custom PCB so it fits correctly inside the target enclosure with proper mounting, connector alignment, and manufacturing-ready layout files. I have experience with embedded PCB design, compact board layouts, enclosure-constrained electronics, connector placement, mounting holes, keep-out zones, power routing, sensor/module integration, and DFM-ready Gerber/BOM preparation. For this project, I will review the enclosure dimensions, mechanical drawings or STL/STEP files, required components, connector openings, button/display positions, and mounting method before finalizing the PCB outline and layout. I will make sure the board fits physically, aligns with the enclosure features, and remains practical for assembly, testing, and future revisions. Final deliverables can include the updated schematic, PCB layout, Gerber files, drill files, BOM, pick-and-place files, and 3D PCB export for enclosure verification. I can also provide a quick fit-check review using the enclosure model before release to manufacturing. Regards.

⭐⭐⭐⭐⭐ I've carefully reviewed your requirements, and this is exactly the type of product-focused PCB project I enjoy. Since the enclosure is already defined, my first priority will be ensuring the PCB aligns perfectly with the STEP model, including the USB-C connector, display opening, buttons, mounting points, and all external connectors. I'll design a clean, production-ready PCB around your ESP32 development board, TFT FPC interface, LiPo charging circuit, USB-C power input, soil moisture sensor connector, and supporting power circuitry. Throughout the design, I'll focus on manufacturability, reliable power distribution, and component placement optimized for assembly. If I identify opportunities to improve cost, reliability, or production yield, I'll review them with you before making any changes. Milestones: Mechanical integration & schematic PCB layout & design review ERC/DRC verification Manufacturing files & documentation A couple of questions: • Which ESP32 30-pin development board model are you using? • Could you share the STEP enclosure and TFT mechanical drawing so I can verify connector placement from the start? I'd be happy to help deliver a production-ready PCB that's ready for commercial manufacturing.

Hi, If you need more than Gerber files — if you need working assembled boards on your desk — I am a strong fit. I combine 14+ years of PCB design and firmware work with real manufacturing experience inside a Shenzhen PCB factory. I previously worked at READA PCB Technology in Shenzhen as a PCB designer, production manager, and manufacturing coordinator. I know how designs are quoted, fabricated, assembled, inspected, and shipped — so I can manage your project from schematic to tested units without losing time between separate vendors. What I can deliver: • Schematic and PCB layout (Altium, KiCAD, or Eagle) • DFM/DFA review before release to production • PCB fabrication and PCBA coordination • Component sourcing and BoM optimization • Functional testing against your test specification • Fast shipping for prototype and small-batch runs I also work with JLCPCB, PCBWay, and Seeed Studio when clients prefer those channels, but my advantage is firsthand factory knowledge from READA and a single point of contact through design, assembly, and debug. I have designed and manufactured IoT controllers, LTE HATs, OBD boards, and mixed-signal embedded products. I can share relevant examples once we connect. Tell me your target quantity, timeline, and whether components are consigned or fully sourced — I will reply with a clear path to first article. Best regards, Ting
