Hi, Most issues in ESP32 + USB + RS485 boards are not schematic errors-they come from poor grounding, routing, and noise coupling, which leads to unstable communication. That’s where I focus. I can review your EasyEDA design and turn it into a stable, production-ready PCB, not just a corrected one. What I will do: - Identify and fix schematic gaps (power, USB, RS485 integrity) - Redesign power path for stable 3.3V operation (ESP32-sensitive) - Optimize USB D+/D− routing and RS485 differential lines - Apply proper grounding, isolation, and EMI/EMC practices - Deliver clean PCB layout in EasyEDA + Gerbers, BOM, Pick & Place I have strong experience in ESP32 systems, communication interfaces (USB, RS485, CAN), and mixed-signal PCB design, including real-world products where stability and noise immunity are critical. This is my advantage: I don’t just “fix”—I improve reliability under real conditions. I can start immediately and deliver quickly with clear updates.
