Hi, I am an experienced Electronics and PCB Engineer with a strong background in ESP32-based hardware, industrial electronics, and safety-critical control systems. I can design a reliable 24/7 traffic light controller PCB capable of handling 220 VAC LED modules with continuous operation. The main PCB (PCB1) will manage all logic and safety functions, including fail-safe architecture, external watchdog, master relay cut-off, and proper OE handling for the 74HC595 shift registers controlling relays. Additional PCBs (PCB2, PCB3, etc.) can be seamlessly connected to expand relay channels. I will ensure strict separation of HV and LV sections, proper creepage/clearance, and DRC-compliant PCB layout in EasyEDA. The design will include flyback protection, lamp current monitoring, and robust connectors for industrial reliability. You will receive complete schematics, PCB layout, BOM, and assembly-ready files ready for production deployment.

Hello, I’ve read your brief on a 24/7 ESP32-based traffic light controller with mains connectivity and a fail-safe mindset. I’ll design a reliable main PCB and slave boards with proper isolation, robust power conditioning for 220VAC LED modules, and a dependable ESP32-based control loop. I’ll emphasize a clean schematic, clear bill of materials, and a layout that minimizes noise, includes watchdog/soft-fault handling, and supports easy EDAs for future revisions. Delivery will be concise, tested in stages, and documented for quick field debugging. I’ll provide a compact reference design, ready for layout in your preferred EDA tool, and a clear signal/trigger scheme for interconnects between PCB1 and additional boards. Design a brief, targeted question about the project’s specific safety standards and ESP32 module preferences to involve the client. Best regards, Marko Aleksic
