Prototype Wearable Massage Device Assembly
Budget: ₹1,500 – ₹12,500 INR
I’m building a first–run prototype of a soft, coin-vibration massage wearable and need the electronics fully assembled and proven on a single-layer FR-4 board with comfort-centric routing. The core bill of materials is locked:
• Li-Po 3.7 V / 400 mAh
• USB-C charge-in with dedicated charging IC
• Low-power MCU, two MOSFET drivers, 10–12 mm coin vibration motors
• 3 white LEDs + 1 bi-color status LED
• One tactile push-button, assorted Rs/Cs, NTC, PTC, TVS
• EVA isolation mounts, grommets, wires, connectors
What matters most is comfort and ergonomics, so component placement, wiring exits, and vibration isolation must support a slim, body-friendly form factor. I’ll supply the components for each part; you’ll handle:
1. Schematic capture and 1-layer PCB layout that respects motor EMI and USB-C trace guidance.
2. Population, reflow/solder, and continuity testing.
3. Firmware stub that confirms charging, button press, LED indications, and three vibration patterns.
4. Bench verification video showing current draw, charge cycle, and motor activation.
The job is complete when a working board, ready for strap-mounting, passes those tests and ships back to me. Feel free to suggest minor footprint tweaks if they improve comfort without increasing thickness.
