About the job
Project Title: KiCad Schematic & PCB Design for Wrist-Worn NIR Sensor (1300 nm LED, Interstitial Fluid)
Description: We’re developing a wrist-worn sensor using NIR spectroscopy (1300 nm LED) to measure blood alcohol concentration (BAC, 0–0.2%) via interstitial fluid for research/clinical use. We need a KiCad designer to create a schematic and 2-layer PCB (20 x 20 mm) for a 30 x 30 x 10 mm wristband. The design includes a 1300 nm LED, InGaAs photodiode, ESP32, sensors (temperature, humidity, accelerometer), amplifiers, and power management, using interstitial fluid detection (no vapor chamber). Deliverables: KiCad files, Gerber files for JLCPCB, BOM CSV, STEP file, PNG mock-ups. Budget: $200–$400 USD, timeline: 10–14 days (start June 10, 2025).
