Jiyoung P.
Production-ready Embedded System Design - ESP32, ESP8266, STM32
⚡ From prototype to production-ready PCB — fast, clean, and ready to order. 🏃♀️ Whether you're validating a concept on a breadboard or shipping your first production run, I bridge that gap. Send me your idea. I'll tell you exactly what it takes to build it. I design embedded hardware that goes straight to manufacturing. You get files that upload to JLCPCB, and assembled boards show up at your door — no sourcing headaches, no manual soldering. 🔧 What I deliver: → Schematic + PCB layout in KiCad → Gerber, BOM (LCSC part numbers), pick-and-place — JLCPCB turnkey-ready → Firmware when needed (ESP-IDF, Arduino, STM32 HAL) → Clean documentation so your next engineer can pick up where I left off 🛠️ Core stack: → MCUs: ESP32, ESP8266, STM32, RP2040 → Connectivity: WiFi, BLE, LTE (SIM modules) → Power: Buck converters, LDOs, battery charging, protection circuits → Sensors: Temperature, humidity, IMU, current sensing, analog front-ends
