Hello, I can complete both EasyEDA boards quickly with a clean JLCPCB-ready approach, focusing on reliability, correct power conditioning, and practical RS485 network deployment rather than overcomplicating the design. Scope understanding: • Board 1: ESP32 + W5500 Ethernet + MAX3485 RS485 + 12V input power stage • Board 2: CH32V003F4P6 + MAX3485 + 12V input power stage + required I/O integration Key implementation priorities: • Proper ESP32 boot/reset circuit • W5500 SPI routing and decoupling • CH32V003 stable programming/debug header • RS485 termination/biasing options • Reverse polarity + input filtering • AMS1117 thermal considerations (or better regulator suggestion if current demands justify) • JLCPCB/LCSC part optimization • Compact, production-friendly routing Deliverables: • EasyEDA source files • Schematic + PCB • Gerbers • BOM (JLCPCB parts) • CPL / Pick & Place • Pinout summary I understand both ESP32 and CH32V003 ecosystems and can keep the design straightforward, manufacturable, and quickly executable within your timeline. If your “+2” on Board 2 refers to additional outputs/interfaces, I can integrate them cleanly during review. Best regards, Engr. Muhammad Uzair

Hi, This is actually one of the latest projects I worked on — ESP32 with RS485/Ethernet communication and compact industrial-style PCB integration. You can also see ESP32-based designs in my portfolio, and I have experience working with the CH32V003F4P6 as well. I can design both EasyEDA boards quickly and make them fully JLCPCB-ready, including proper routing for ESP32, W5500, RS485, regulators, and production files. Deliverables include schematic, PCB layout, Gerbers, BOM, and CPL files. Best regards, Ahmed

Hello, I have a strong electronics and VLSI background with hands-on experience in PCB design, embedded systems, and hardware interfacing. I have worked with ESP32-based systems, power regulation circuits, communication interfaces like RS485, and custom PCB development workflows. I can design both boards in EasyEDA and prepare them fully JLCPCB-ready within the required timeline: • ESP32 + W5500 + MAX3485 master board • CH32V003F4P6 + MAX3485 slave board The design will include: • Proper power routing and AMS1117-3.3 regulation from 12V • Clean RS485 signal interfacing and termination considerations • Compact and reliable PCB layout • Correct decoupling, grounding, and connector placement • JLCPCB manufacturing-ready Gerber files and BOM if needed Since the design is relatively straightforward and I already understand the components involved, I can complete it quickly while ensuring reliability and readability in the schematics/layout. I have reviewed the project description and understand the urgency. Ready to start immediately. Best regards, Rayi Giri Varshini
