Skilled PCB Designer for Production-Ready Board

@PathumSudarshana

I’d be happy to design this board for you. I’ve worked on production-ready ESP32 power boards with USB-C input and high-current 5V distribution, so I’m comfortable designing a stable, efficient 5V rail capable of handling 5A and around 20W total load. I pay close attention to trace sizing, copper thickness, thermal performance, and proper grounding to make sure the board works reliably under real-world conditions. I’ll design a solid USB-C PD input stage, efficient buck conversion to 5V, and proper protection (overcurrent, short-circuit, and input protection). The 8-pin ports will use locking, high-current board connectors suitable for secure cable connections. You’ll receive a complete schematic, clean compact PCB layout, LCSC-based BOM, Gerbers, pick & place, 3D files, and fully JLCPCB-ready manufacturing outputs.

Hello contractor, From what I can gather, you need a PCB designer to integrate all the features into a PCB, ready for manufacturing. Regarding my background, I have almost 10 years of experience in Schematic and Layout desing. I have worked in consumer, industrial, automotive and medical electronics. I am very familiar with USB-PD standard. I have designed powerbanks for USB up to 65W and devices that use USB-PD up to 100W to charge. I have experience with production and supply chain, EMC certifications and CE marking certifications for both consumer and medical devices. I believe I am a good fit for your project and looking forward to answer your questions.

With extensive knowledge and experience in electronics, embedded systems, PCB design, and microcontrollers, I am your ideal candidate for this project. My expertise in hardware design and deep understanding of USB-C PD power systems will enable me to deliver a clean, compact, and highly efficient PCB that meets all your requirements. Having worked with C, Arduino, ESP32, STM32, and other microcontroller platforms throughout my projects as an Embedded Systems Engineer, I am well-versed in designing for high-current capacity like you're requiring. I specialize in maximizing power distribution capabilities while prioritizing stability and safety. Additionally, my proficiency using KiCad and EasyEDA pro - circuit simulation and PCB design tools - allows me to create professional quality designs ready for small-batch production. My skills extend beyond just Hardware design. I also have a background in Software Engineering and AI & Python Development which comes handy when combining AI solutions with hardware. Such capability could prove valuable for future enhancements of the board or even the possibility of creating an automated testing system for mass production of the boards.

Hi, I can design this production-ready carrier board for your S3-N16R8, ensuring robust power delivery and signal integrity. I will implement a USB-C PD sink controller to negotiate the required voltage and a high-efficiency buck converter capable of a sustained 5A output for your 5V rail. For the connectors, I recommend Molex Micro-Fit 3.0 or JST-PH/XH variants rated for your current needs to ensure secure, locking connections. My design process includes rigorous thermal management, calculated trace widths for 20W loads, and a complete JLCPCB-ready manufacturing package including BOM and 3D renders. I have extensive experience with ESP32 integration and high-current DC power distribution and look forward to delivering a professional, compact solution for your project. Best regards
