I need a compact, low-power PCB that turns my smartwatch concept into a reliable health-monitoring device focused on tracking sleep patterns. The board will host the core microcontroller, Bluetooth LE, battery management, and the sleep-sensing components while still fitting comfortably into a slim wearable enclosure. Key requirements • Primary purpose: health monitoring with emphasis on accurate, real-time sleep analysis. • Metrics: sleep patterns only; no heart-rate or SpO₂ circuitry is necessary at this stage, which should help keep size and cost down. • Sensor choice: I have not locked in a specific sensor set, so I’m open to your recommendations—whether an accelerometer, gyroscope, PPG, or a clever combination—to obtain reliable sleep-stage data. • Form factor: round board no larger than 28 mm in diameter, ideally with all components on one side to simplify assembly. • Power: designed for 7–10 days operation on a 200–250 mAh Li-ion coin cell, so every milliamp counts. • Wireless: Bluetooth Low Energy (BLE 5.0 or later) for syncing data to a mobile app. Deliverables you’ll provide 1. Complete schematic in Altium, KiCad, or Eagle (your choice, but please state it up front). 2. PCB layout ready for fabrication, including Gerber, drill, pick-and-place, and assembly drawings. 3. BOM with manufacturer part numbers, availability status, and indicative pricing. 4. Design report outlining sensor selection rationale, power budgeting, and any expected RF considerations. 5. One round of post-fabrication tweaks after initial prototypes if required. I’ll supply the mechanical envelope and battery size constraints once we start. If you’ve previously squeezed BLE radios and precision analog front-ends into tiny wearables, I’d love to see those examples.

I have designed and shipped a compact BLE wearable PCB before — a round multilayer board with nRF BLE SoC, 3-axis IMU, coin-cell power management targeting 9–12 month battery life, and sub-28mm layout, designed in KiCad and fabricated through PCBWay. The exact constraints you've described. See digitalmonk.biz. Sensor recommendation for sleep-only monitoring: LIS2DW12 accelerometer + nRF52810 BLE SoC — no PPG needed for sleep-stage classification via wrist movement. Deep-sleep current <2µA (accelerometer in low-power mode, BLE in PSM), active burst <5ms per sample. On a 200mAh cell this comfortably exceeds your 7–10 day target. For this board I will: • nRF52810 with 50Ω trace antenna + keepout, LIS2DW12 on SPI with motion-threshold wakeup interrupt • LiPo charge IC (MCP73831), single-sided 28mm round layout in KiCad • All components on one side, DRC clean, Gerbers + drill + pick-and-place + assembly drawing • BOM with MPN + pricing, design report: sensor rationale, power budget, RF considerations Delivery in 2 days. Shall I include a USB-C charging pad on the board edge, or is wireless/pogo-pin charging preferred?

we have previously worked with such projects , we can go at it with these choices: 1) low cost MCU but firmware development might take more time (preferabbly wch ble chips) 2) standard nrf5x series MCU , higher initial cost , firmware development should be easier and faster we have previously worked with both these MCUs , using chip or pcb trace antenna
