Looking for Experienced PCB Design Engineer (Schematic + Layout)

@markoa7

Hello, I’ve reviewed the project scope and I can contribute with a practical, production-forward PCB design approach. I will start by auditing and refining the existing schematic, then design a reliable 2-4 layer layout with solid grounding, proper power routing, and signal integrity for the MCU(s) you’re using (ESP32, STM32 or similar). I’ll select components and stock from KiCad/Altium/EasyEDA-appropriate suppliers (focusing on JLCPCB/PCBWay availability), generate manufacturing-ready Gerber files, and assemble a complete BOM with manufacturer part numbers. The workflow will emphasize clean power delivery, controlled impedance where needed, and clear documentation to ease mass production. Deliverables will include final schematics, PCB layout, Gerbers, fabrication package, and BOM. What is the target production quantity and any preferred ESP32/STM32 variant or specific MCU features (wifi, dual-core, cryptography) to guide component selection and power design? Best regards, Marko Aleksic

Hello, I have worked on many industrial and automotive projects using protocols based on CANbus, RS485, RS232, etc. I also design/program modules using SPI/I2C. I am familiar with many microcontroller families such as ESP32, STM32, AVR, etc. I will ship the complete project package, including Gerber files, BOM, and pick-and-place options, so you can order directly from JLC. Looking forward to your reply.

Hello, I’m an experienced PCB design engineer with a strong background in power electronics, embedded systems, and production-ready hardware design. I can support your project from schematic review through to finalized manufacturing files, ensuring the board is reliable, scalable, and ready for mass production. I have extensive experience working with ESP32, STM32, and similar MCUs, including designs that involve UART, I2C, SPI, CAN, and RS485 communication. My approach to PCB layout focuses heavily on proper grounding strategy, controlled return paths, clean power routing, EMI reduction, and thermal considerations—especially important in 2–4 layer designs. For your project, I will: Carefully review and optimize your existing schematic (protection, decoupling, power integrity, signal routing) Design a well-structured multilayer PCB with strong DFM compliance Select reliable components available from JLCPCB or PCBWay to streamline assembly Deliver complete manufacturing documentation: Gerbers, drill files, pick-and-place, assembly drawings, and a detailed BOM with verified manufacturer part numbers I work primarily with KiCad and follow a disciplined workflow that ensures consistency between schematic, layout, and fabrication outputs. If you share your current schematic or system requirements, I can provide initial technical feedback and outline the best approach for layout and production.

Hello, This is a proper production-grade PCB task — not just routing traces. I’ve worked on 2–4 layer boards using KiCad and Altium Designer, including ESP32/STM32-based designs prepared for JLCPCB mass production. How I’d approach your project: 1. Schematic Review • Power architecture validation (LDO/DC-DC efficiency, ripple control) • Decoupling strategy near MCU • Protection circuits (ESD, TVS, reverse polarity if required) 2. PCB Layout • Dedicated ground plane (solid reference layer) • Controlled power routing + current path analysis • Proper crystal placement + short return loops • Isolation for analog/digital sections if needed • Differential pair routing (CAN/RS485 if applicable) 3. Production Prep • JLCPCB/PCBWay stock-aligned BOM • DFM check • Assembly drawings + pick & place • Clean Gerber + fabrication package I design for manufacturability — not just functionality. Timeline: 7–14 days depending on complexity Budget: $180–250 Quick question: what’s the primary voltage domain (5V, 12V, battery)?

Hello, Having dedicated my career to hardware design and embedded systems for well over a decade, I can confidently assert that I am the right choice for your PCB Design Engineer needs. My team of seven experienced engineers, combined with my in-depth knowledge of Altium, STM32CubeIDE and ESP-IDF will ensure not just crisp PCB layouts and robust schematics, but also the provision of manufacturing-ready files of the highest quality suitable for mass production. Another strength we bring to the table is our proficiency in communication protocols including USB and SPI and motor control which are must-haves for IoT devices. We won't just conduct superficial revisions to your schematic or prescribe arbitrary parts from generic stock. Rather, we'll dig deeper, actively reviewing your current system, identifying any areas that can be improved and providing the best recommendations respectively. A testament to my expertise involves overseeing notable projects incorporating microcontroller platforms such as Arduino, ESP32, STM32, including yours truly as a core designer. In short, my versatile skill set in integrated hardware design, extensive experience with electronic manufacturing techniques, and proficiency with coding languages like C++, make me an excellent candidate for this project. By selecting me, you're not just acquiring a professional with knowledge of industrial standard PCB layout tools but someone committed to giving you a tai Thanks!
