Custom Wearable Sensor PCB Design

I’m consolidating the electronics of my wearable prototype into one slim, production-ready board. Right now the device is a stack of breakout modules—an ESP32-C3 Xiao Seed carrying the brains, a BMI160 six-axis accelerometer/gyroscope, and a couple of resistors & a capacitor. I need a single PCB that folds all of that functionality together while preserving motion-sensing accuracy and rock-solid wireless communication.

Here’s what I’ll hand off to fabrication once we’re done:

• A complete, reviewed schematic that marries the ESP32-C3 Xiao Seed with the BMI160 (and any supporting passives, regulators, antennas, USB-C circuitry, etc.).
• Production-grade Gerber, drill, pick-and-place, and centroid files, plus a clean BOM ready for my assembler.
• Any custom footprints or libraries you created, so I can revise the design in KiCad down the road.

I’ll provide the current breakout board wiring and pin mappings; you streamline the layout, handle power integrity, antenna clearance, and keep the whole board as compact as practical for a wrist-mounted enclosure. A brief bring-up guide or test points call-out would be the final cherry on top.

If this sounds right up your alley, let’s jump in.
