Hi, I’m a PCB Design Engineer with 8+ years of experience in schematic design, multilayer PCB layout, embedded hardware, and production-ready designs using KiCad and Altium. I have hands-on experience with JLCPCB/LCSC, including Basic Parts selection, BOM optimization, footprint verification, DRC/DFM, Gerber/Drill, CPL/P&P generation, and component rotation/polarity validation. I can take your design from block diagram → schematic/BOM → 2/4-layer PCB → DRC → JLCPCB production package, including STEP and complete editable KiCad files. Proposed milestones: 1. Schematic & BOM 2. PCB Layout & DRC 3. Gerber/CPL/Production Validation Estimated turnaround: 2–3 weeks. Best regards, Muhammad Adeel

@Mahmoud00Ibrahim

Your job caught my eye — turnkey JLCPCB packages with milestone-based delivery and strict IP/license terms are exactly how I like to work. 50+ commercial hardware projects done, including 20+ ESP32-based boards now shipping in production. I just finished a board with an STM32H745 + ESP32-S3 co-processor, sensors, and power management — very close to what you're describing. JLCPCB SMT rules, LCSC/Basic Parts selection, and CPL rotation/pin-1 alignment are routine for me, not a learning curve. No issue keeping everything to permissive licenses (MIT/Apache/BSD/CERN-OHL-P), and I'm happy to sign an NDA/IP agreement before starting. You'll get the full native KiCad project, custom symbols/footprints, Gerbers + drill files, a normalized BOM with LCSC part numbers, verified CPL file, STEP model, and a clean DRC report — gated across your three milestones (schematic/BOM → layout/DRC → final production files).

@mcollinscalz

Hello my name is Collins and the board you describe is one I have already built. My NICU patient-monitoring design is an RP2040 around I²C and One-Wire sensors, a DS18B20 temperature sensor, an INA219 current and voltage monitor and an SpO₂ probe, with a Li-ion charge and protection circuit. I authored the schematic and the layout, verified decoupling and signal integrity, then brought the hardware up and debugged it in circuit. Item 12, confirmed. I design to JLCPCB DRC, select against live LCSC stock, and I have ordered and had boards assembled through their SMT service. In practice that means Basic Parts for passives so you are not paying feeder setup on every 0402, Extended parts only where a function genuinely needs one, and availability checked at BOM freeze rather than at order time. I lay out 4-layer with a continuous ground reference and proper plane decoupling, and keep placement single-side wherever the design allows it. Milestones, matching your structure: Schematic capture and BOM selection, five working days from block diagram Layout, DRC pass and 3D clearance check, seven to ten days Production package and CPL validation, three days You receive the complete editable KiCad project with all custom symbol and footprint libraries, Gerbers and Excellon drills, a normalised BOM carrying LCSC part numbers, a verified CPL, the STEP model and a passing DRC report.

@mohammadusman45

Hi, This is a well-scoped project, and I appreciate that you've laid out the full deliverable set and manufacturing constraints up front **Schematic Capture (1):** I'll build modular, production-ready schematics in the latest stable KiCad release, structured around standard commercially-permissive reference designs for your MCU choice (ESP32/RP2040/STM32) and the associated sensor/power management interfaces — hierarchical sheets separated by functional block (power, MCU core, sensor interfaces) for clarity and easier future revision. **PCB Layout & Routing (3):** I'll target 2-layer or 4-layer stack-up per your final component/EMI requirements, with clean DRC compliance to JLCPCB's published design rules, proper decoupling placement close to each IC's power pins, thermal relief on through-hole/ground connections, continuous ground plane, and single-side SMT placement wherever the design permits to minimize your assembly cost. I'd welcome a quick call to review your block diagram and sensor/power requirements before finalizing a firm timeline and fixed-price quote per milestone. Looking forward to working together. Best regards, Muhammad Usman

@alluankit01

Hi, I can take your embedded hardware design from block diagram/specification to a complete KiCad production package optimized for JLCPCB SMT assembly. The best solution is to first review the product requirements, MCU choice, sensors, power rails, board size, connector needs, and JLCPCB assembly limits. Then I’ll prepare modular schematics, select LCSC in-stock components with Basic Parts where possible, complete a DFM-focused 2/4-layer PCB layout, and verify BOM/CPL orientation for JLCPCB placement. I’m comfortable with KiCad schematic capture, ESP32/RP2040/STM32-style boards, sensor interfaces, power management, LCSC component selection, JLCPCB SMT rules, single-side SMT placement, DRC cleanup, Gerber generation, BOM normalization, CPL rotation correction, and STEP export. Deliverables will include: * Editable KiCad project files * Custom symbols/footprints if required * Production schematic * 2/4-layer PCB layout * LCSC/JLCPCB-ready BOM * CPL/Pick-and-Place file * Gerber and drill files * KiCad DRC report * 3D STEP model * Fabrication/assembly package Suggested milestones: 1. Schematic + BOM review 2. PCB layout + DRC pass 3. Final Gerber/BOM/CPL/STEP validation I’ll focus on a clean, manufacturable, cost-conscious design with proper routing, grounding, decoupling, and complete source-file handover under your NDA/IP terms. Best regards Ankit

@hamzaePCB

Hi, I carefully reviewed your project description and the attached Cold-Chain Data Logger BOM, and I’m very interested in this project. I understand the architecture around the Fanstel BT832 (nRF52832) BLE module, TMP117 I²C temperature sensor, W25Q16 SPI Flash, reed switch, CR2477 battery and Tag-Connect SWD interface. I have worked through the complete PCB development cycle on multiple projects, from schematic design and component/footprint selection to placement, routing, DRC/DFM verification and final manufacturing files. I work with KiCad and can prepare the complete JLCPCB production package. For this board, I will focus on BT832 antenna placement/keep-out, TMP117 placement, low-power operation, decoupling, ground continuity, compact routing and LCSC/JLCPCB component availability. I can follow your 3 milestones: schematic & BOM → PCB layout & DRC/DFM → Gerber, BOM, CPL, STEP and final production validation. One detail I noticed: the product is described as a Temperature & Humidity Data Logger, but the BOM includes TMP117 for temperature and no dedicated humidity sensor. Should humidity measurement also be integrated? Best regards, Hamza

@VictoriaZ54

Hi, I can take your embedded hardware design from specifications through a complete KiCad production package, including schematic capture, BOM selection, PCB layout, DFM optimization, and JLCPCB-ready assembly files. I’ll focus on reliable MCU integration, sensor interfaces, power management, clean routing, and cost-effective component selection using available LCSC/JLCPCB parts. I can deliver the complete editable KiCad project, custom libraries, Gerber and drill files, BOM with LCSC part numbers, CPL pick-and-place files, populated board STEP model, and verified DRC report. I’ll follow JLCPCB SMT requirements, optimize assembly costs, check polarity/orientation, and keep the design organized for future revisions. Question: Do you already have the initial block diagram, target MCU/sensor selections, and preferred PCB size or enclosure constraints to begin the schematic architecture? Best regards

@HeyAbhinav

Greetings, I reviewed the PDF you shared. Proposed Design: 4-layer PCB with onboard antenna for nRF52832 with impedance matching and pi-filter implementation. As we need a commercial design for production I would adhere strictly to the industrial EMI/EMC compliance and personally validate DFM with the JLCPCB's process. I'm proficient in KiCad and will deliver production-ready gerber and design files to you. We can work with any microcontroller of your choice, though ESP32 is best if you need WiFi connectivity, RP2040 is excellent in terms of cost-to-performance ratio, and the STM32s are industrial workhorse as always. Please have a look at the example designs here https://www.freelancer.com/u/HeyAbhinav. Let's talk and work it out. Cheers!

@kobayasyk

hello, thanks for checking my proposal. I reviewed the provided cold-chain logger BOM. The current design uses the BT832/nRF52832 module with TMP117 temperature sensing, W25Q16 flash, reed-switch input and CR2477 battery power. I can take this into KiCad, complete the schematic and DFM-focused PCB layout, select JLCPCB/LCSC-ready parts, then verify DRC, BOM/CPL rotations and generate the full Gerber, drill, STEP and editable production package. I’ll keep the design focused on reliable RF layout, low-power operation and straightforward JLCPCB assembly.
