Thomas U.
Industrial PCB Designer | Power Supplies & RS485 Systems
I design robust, industry-grade electronics for real-world industrial use — not hobby boards. My core strength is PCB design for industrial systems, with a strong focus on reliability, clarity, and real-world use. I work primarily with 24 V industrial environments, analog signal conditioning, RS485 communication, and power electronics. I specialize in: Industrial PCB design (2–4 layers) 24 V → 12 V / 5 V / 3.3 V power supplies 4–20 mA and 0–10 V signal conditioning RS485 / Modbus-ready hardware MCU-based designs (ESP32, STM32, AVR) KiCad schematics, layout, BOMs, and documentation My designs are made to be: Easy to manufacture Easy to debug Easy to reuse as building blocks I often build modular reference designs (PSU boards, signal boards, IO boards) that clients can reuse across multiple products — saving time and cost. If you need hardware that works outside the lab — let’s talk.
