I have strong experience with low-power BLE hardware and battery-operated IoT devices, including Nordic nRF52-series layouts, SPI peripherals, sensor integration, and production-oriented PCB development. For this design, the critical areas are RF layout quality, coin-cell peak current handling, sleep-current optimization, and stable SPI Flash operation. I would design the board with controlled RF grounding, proper antenna matching, ultra-low-leakage power architecture, and optimized decoupling to realistically target sub-5µA deep sleep current. The deliverables would include full schematic, compact 2-layer PCB, Gerbers, drill/CPL files, BOM with exact MPNs, SWD/test-point access, and DFM-ready layout suitable for JLCPCB/PCBWay and scalable manufacturing.

⭐⭐⭐⭐⭐ I’ve carefully reviewed your requirements, and this project aligns well with my experience designing low-power embedded and wireless hardware for production environments. Your sensor node combines several critical design areas—ultra-low-power operation, Nordic BLE integration, SPI Flash storage, RF layout, and manufacturability. Achieving a deep-sleep current below 5µA while maintaining reliable BLE performance on a CR2032/CR2050 requires careful attention to power architecture, component selection, leakage paths, and peak current management. For this project, I can deliver: • Complete schematic (PDF + editable source files) • Compact 2-layer PCB layout optimized for BLE RF performance • Antenna implementation with matching network recommendations • Gerber, drill, and manufacturing files ready for PCBWay/JLCPCB • Pick & Place / Centroid files for SMT assembly • Detailed BOM with manufacturer part numbers • SWD programming and production test points • DFM review for scalable manufacturing (1,000+ units) Proposed Milestones: Architecture review & schematic design PCB layout & RF optimization DFM review & manufacturing package Final deliverables & revision support A couple of questions: Do you have a preferred EDA platform (Altium, KiCad, EasyEDA)? Will the accelerometer data be stored continuously, or event-triggered to further reduce power consumption? I’d be happy to discuss the power budget and storage calculations before we begin.

Hi, We are available to take this on and get your motion-tracking sensor node working perfectly. The main issue with compact IoT designs is usually power rail decoupling and impedance matching for the nRF52810 specifically. Are you planning to use a ceramic chip antenna for the 25x25mm footprint, and do you want the test points routed for a specific pogo-pin programming jig? We recently developed a similar ultra-low-power tracking node for a logistics firm that needed extended battery life on a coin cell. We used the nRF52810 architecture to hit deep sleep targets and integrated SPI Flash for reliable data logging. We corrected their PCB layout to ensure the antenna matched correctly across the board, which eliminated signal loss. Our design optimization stopped their battery drain issues during sync and made the production assembly process significantly more efficient for their team. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions
