Motion-Tracking Sensor Prototype

I’m developing a compact, sensor-based device whose sole purpose is accurate movement tracking. I already have the core concept and need someone who can turn it into a fully functioning prototype—including schematic capture, PCB layout, firmware, and a testable board.

Here’s what I need you to cover end-to-end:
• Component selection and schematic for a motion sensor (an accelerometer/gyro combo is fine, but I’m open to other ideas that meet tracking accuracy and power goals).
• A two-layer (or better) PCB that keeps the footprint small and components readily sourceable.
• Embedded firmware that initializes the sensor, filters raw data, and exposes clean XYZ movement data over a simple serial or BLE link we can log on a laptop or phone.
• Bench validation: basic calibration routine, sample data plots, and confirmation the board survives normal handling.
• Manufacturing files—Gerbers, BOM, pick-and-place, compiled firmware, and a brief bring-up guide.

I’ll provide any high-level mechanical constraints and branding assets once we start; you handle the electronics and code. If you have quick-turn PCB assembly contacts or can hand-assemble the first couple of units, mention that—it’s a plus.

The project wraps when I have a turnkey prototype in hand, running firmware that streams reliable movement data for at least 30 minutes on the bench without crashing.
