@yaroslavmark

✅ Okay, I got what you want exactly. ❤️ I am a professional engineer PCB Designer & Embedded Engineer with over 10 years of experience, providing schematic capture, KiCad PCB layout, and robust industrial embedded hardware design. In my opinion, this project calls for a thoughtful high-reliability PCB solution that balances communication interfaces (ESP32, RS-485, LTE) with industrial-grade protections. I would ensure proper isolation, surge/ESD suppression, and clean power delivery across all modules while keeping the design manufacturable and testable. The gateway will be built with clear attention to EMI control and real-world industrial deployment requirements. This project is very similar to my previous works. I recently completed a KiCad-based industrial IoT gateway design integrating Wi-Fi/Cellular modems and isolated RS-485 interfaces, and I worked on a custom ESP32 industrial controller board for a manufacturing client with complete BOM, Gerbers, and test documentation. ✅Steps: ⚡ Step 1: Capture complete schematic including ESP32 module, RS-485 transceiver, LTE modem, power supply, FRAM, connectors and necessary protection peripherals. ⚡ Step 2: PCB layout in KiCad with rule-based placement, isolation zones, routing for high-speed and power nets, and incorporation of test points and mounting features. ⚡ Step 3: Deliverables packaging — full KiCad project files, Gerber/Drill files, BOM, pick-and-place data, and layout notes on isolation/ESD considerations.
