Hardware Designer – Wearable BLE Device (PCB + Enclosure)

@engrusmanfaiz

Hello, I can deliver a complete wearable BLE solution combining compact RF-optimised PCB design with a clean, production-ready enclosure. I have extensive experience with nRF52 series designs, including bare SoC layouts, antenna tuning, and low-power wearable systems. For your 30–35mm circular PCB, I will ensure controlled impedance, proper RF grounding, and antenna clearance to maximise BLE range and stability. I will select optimal components (fuel gauge, charger, haptic driver, LDO) fully aligned with JLCPCB/LCSC for seamless PCBA. My enclosure approach focuses on ergonomic bracelet integration, precise internal stacking (battery + PCB + motor), and DFM-ready geometry for SLA/FDM and future injection moulding. You will receive 2–3 refined enclosure concepts with STEP/STL, balancing aesthetics and manufacturability. I prioritise first-pass success, ensuring PCB + enclosure fit without rework through accurate 3D co-design. Typical timeline: 10–12 days PCB + 5–7 days enclosure; fixed price can be finalised after brief spec alignment. I will share relevant BLE and compact device design samples upon request. Confident to deliver a stable, elegant, and production-ready wearable system. Regards, Engineer Muhammad Usman Hardware & Embedded Systems Developer (12+ Years Experience)

Having recently completed a compact health tracker using the nRF52832, I understand the delicate balance between antenna performance and ultra-small form factor constraints in wearable tech. I can deliver a refined, production-ready solution that integrates a high-density PCB with a custom-fit, ergonomic 3D enclosure. My experience spans the entire lifecycle from schematic capture to DFM-compliant housing, ensuring your device isn't just a prototype, but a scalable product. I focus on optimizing the Bill of Materials to reduce unit costs while maintaining the high reliability required for body-worn electronics. For the electronics, I will utilize Altium Designer to manage a 4-layer stack-up, prioritizing signal integrity and optimizing power management for maximum battery longevity. I’ll implement a custom PCB trace antenna or a chip antenna depending on your range requirements, verifying the RF path with precise impedance matching. Simultaneously, I will design the enclosure in Fusion 360 using master modeling to ensure the PCB fits perfectly with zero mechanical interference. This dual-track approach allows for immediate validation of the internal layout against the external industrial design, reducing the need for costly iterative prototyping. To ensure the architecture hits your target specs, do you have a specific battery capacity in mind or a preferred BLE SoC like the Nordic nRF52 series? Furthermore, are there specific environmental ratings like IP67 water resistance that the enclosure must meet? I am available for a brief call to discuss the component selection and mechanical constraints to align on a roadmap—let’s connect to turn this wearable concept into reality.
