Hi There! As you can see in my portfolio on my profile, I have extensive experience designing PCBs and mass production equipment, just like you need. I can handle your project. I know you're probably tired of reading AI-generated proposals, and I'd rather not waste time on that. If you're interested in working with me, send me a message and we can work out the details! I already have a recently designed system with LAN8720 and KSZ8863, I understand your needs because I've seen several similar EVSE projects recently. Best Regards!

Your search for a highly competent and experienced PCB designer specialized in integrated hardware systems ends here. As an adept multitalented freelancer, I am well-versed with the intricacies of circuit design, electronics, embedded software and systems, as well as IoT hardware manufacturing using tools such as KiCad. Combining these skills with my affinity to build advanced AI systems that work at production level, my profile is a unique blend you won't find easily. With my hands-on experience in ESP32 and STM32 firmware development and proficiency in adhering to EMI/EMC standards for EV chargers, I can ensure your universal EVSE controller PCB design will be scalable enough to facilitate not just the existing requitements but also anticipated future upgrades like OTA updates, QR charging, load balancing and ISO 15118 support. Moreover, as an Odoo ERP end-to-end implementer proficient across React, Flutter, Django and more—your productivity will be boosted by getting access to not just a system specific approach but a holistic one marrying the exact needs of your project. If you desire nothing short of impeccability in your project—let's talk further about how we can bring your vision into reality—I'm excited and ready!

I am a Senior Hardware Design Engineer with extensive experience in ESP32-based industrial and IoT hardware design. I can design a production-ready universal EVSE Controller PCB supporting 3.3 kW to 22 kW chargers with ESP32, Ethernet, RS485, RFID, CP/PP circuits, safety interfaces, and OCPP integration support. Approach: • Review IEC 61851, AIS-138, and system requirements. • Design modular schematic with ESP32, LAN8720, RS485, RFID, and optional 4G. • Implement CP/PP, contactor control, protection, and sensing circuits. • Develop 4-layer PCB with proper EMI/EMC, creepage, and clearance rules. • Generate manufacturing-ready KiCad files, BOM, Gerbers, and assembly documentation. Looking forward to working with you.

Hi, I can design a production-ready, 4-layer industrial PCB for your universal ESP32 EVSE controller following strict IEC 61851 standards. I will integrate the LAN8720 Ethernet, RS485 Modbus, RC522 RFID, and the 4G module header, ensuring a clear separation between low-voltage control and high-voltage interface sections. The Control Pilot and Proximity Pilot circuits will be engineered with proper creepage, clearance, and EMI/EMC compliance. You will receive complete KiCad source files, schematics, optimized PCB layouts, and full manufacturing deliverables including Gerbers, BOM, and assembly drawings. Best regards
