As both a seasoned Electrical Engineer and Professional PCB Designer, I have dedicated the past 8 years to perfecting my skills in circuit design and fabrication. Having hands-on experience with platforms such as Eagle, Altium, KiCAD, EasyEDA, MATLAB/SIMULINK, and Python, I cover all of your project's requirements. Filigreed projects are where my passion lies and I am no stranger to working with compact mains-powered IoT boards or smart switch designs. One of my core strengths is adhering to strict clearance and creepage rules- ensuring there is always a substantial minimum of 2.5mm spacing between high-voltage AC mains and low-voltage DC logic traces. Investing in safety is paramount and as an experienced designer, I know how to skillfully incorporate Fuse,portection etc and ensure absolute safety for each module deployed. My expertise reaches beyond the mechanics of PCB development; I am also skilled at creating housing designs for PCBs using software like Fusion360 - a highly valuable bonus for this project as we look to optimize on space without sacrificing functionality.I am confident that you won't find many designers who can match my innovative solutions and proven track record of delivering quality designs on time and within budget. The objective of this project resonncates with me significantly and I would love to contribute significantly towards turning your imaginative idea into reality. Let's join hands!

Hi, I can review, optimize, place, and route your compact 55mm × 45mm ESP32 smart relay PCB in KiCad, with careful separation between 230V AC mains and low-voltage logic. The best solution is to first review the schematic, enclosure limits, relay load rating, AC-DC converter footprint, switch input, and protection stage. I’ll then optimize component placement, maintain the required creepage/clearance, define safe mains and logic zones, route suitable trace widths, protect the ESP32 antenna area, and complete DRC/ERC checks before generating production files. I’m comfortable with compact IoT PCB design, ESP32-WROOM-32, isolated AC-DC power supplies, 3.3V regulation, relay switching, fuse/MOV protection, mains separation, EMI-aware routing, thermal considerations, and KiCad production workflows. Deliverables will include: * Schematic review and optimization * Compact dual-layer PCB layout * AC/DC isolation zoning * Relay and switch-input routing * ESP32 antenna keep-out * Gerber and drill files * Pick-and-place files * BOM with manufacturer part numbers * Editable KiCad project * DRC/ERC-checked production package I’ll focus on safety, compact placement, manufacturability, and reliable Wi-Fi performance within the restricted enclosure size.

Hi, I can design this board in KiCad while meeting the 55 × 45 mm size constraint and maintaining proper isolation between the AC mains and low-voltage circuitry. I'd recommend using a certified isolated AC-DC module (e.g., Hi-Link HLK-PM01 or Mean Well IRM-03-5), an ESP32-WROOM-32, MOV + fuse protection, a relay driver with flyback protection, and a high-efficiency 3.3V regulator. I'll optimize the layout for manufacturability, creepage/clearance, thermal performance, and reliable operation. You'll receive the reviewed schematic, PCB layout, Gerbers, drill files, BOM with manufacturer part numbers, Pick & Place files, and 3D renders. I'm available to start immediately.
