As a professional Hardware Design Engineer with 8+ years of experience specializing in up to 8-layer PCBs (high-speed digital, mixed-signal, and power converters), I am well-equipped to deliver your production-ready, stacked ESP32 smart switch. I regularly design compact power and IoT hardware, ensuring strict creepage/clearance isolation for mains voltage (PCB 1) and optimizing capacitive touch trace routing to minimize parasitic capacitance on PCB 2. I will ensure flawless 3D mechanical alignment for the board interconnects. I will deliver flawless, assembly-ready Gerbers, BOM, and CPL files using Altium or KiCad. Let’s connect to finalize the layout. Best regards, Muhammad Adeel

Hello, I am a Hardware Design Engineer with experience in PCB design, schematic review, component placement, routing, prototype testing, and manufacturing file generation. I primarily work with KiCad. Your project is particularly interesting because it involves a stacked 2-board architecture combining high-voltage AC switching and low-voltage ESP32 control, where compactness, safety, and manufacturability are critical. I can assist with: • Optimized component placement and routing for both PCBs • Precise board-to-board header alignment for reliable stacking • Proper creepage and clearance implementation for AC mains isolation • Relay and power supply layout best practices around the HLK-5M05 module • ESP32 RF-aware placement and routing considerations • Reliable capacitive touch pad layout for stable touch sensing • Design for Manufacturing (DFM) and assembly readiness Deliverables will include: • PCB source files (KiCad preferred, EasyEDA if needed) • Gerber and NC Drill files • Pick & Place (CPL) files • Consolidated BOM with manufacturer and distributor part numbers • Final design review before production I would be happy to review the schematics and enclosure constraints before starting to ensure the layout meets both size and safety requirements. Looking forward to discussing the project.

@Shaheers

I already have such a design build sevral years ago, esp32 touch board, little 220 to 5v moule, but i used Traic instead of relays, i can't shere the picture of the project here as no attatchment facality

@djalltra

Hi, I’m an electronics engineer focused on ESP32 hardware, embedded systems, and PCB design for production-ready products. Your smart switch design involves several important layout considerations, including the stacked-board connection, AC/DC isolation, relay routing, and capacitive touch sensing. I can create the PCB layouts for both boards with attention to compact placement, precise header alignment, clean routing, and manufacturability. The mains section will be laid out to maintain proper creepage and clearance distances around the power supply, relays, and terminals, while the logic board will be optimized for stable ESP32 performance and reliable touch-pad operation with minimal noise and parasitic capacitance. I have completed projects involving ESP32 control systems, relay-driven automation boards, environmental monitoring devices, sensor interfaces, and other mixed-voltage PCB designs intended for assembly and production. Deliverables will include the original PCB design files, Gerbers, NC Drill files, Pick-and-Place data, and a consolidated BOM with supplier part numbers for automated assembly. Please send the schematics and enclosure dimensions, and I’ll review the board constraints and stacking requirements before starting the layout. Terlumun

@autocontact51

Dear Sir, I'm very interested in your ESP32-based 4-channel smart switch PCB project — it's exactly the kind of work I specialize in. I'm an IoT engineer with hands-on PCB design experience using EasyEDA, which is your preferred tool. I've worked extensively with ESP32 (WROOM modules), relay driver circuits with MOSFETs, and mixed-signal boards that require careful separation between high-voltage and low-voltage domains . The AC pcb is allready done because i have done similar project for a gate door . Here's what I bring to this project: • PCB layout for both boards with strict attention to High V and clearance distances on the HV (HLK-5M05, relays, MOV) + more safty component if you want i have allready done a similar ac pcb for esp32. • Proper ground plane partitioning and decoupling on the LV side (ESP32, 74HC595, AP2112K LDO) • Capacitive touch pad routing (4 × 10×10 mm pads) with minimized parasitic capacitance for reliable touch detection Since you mentioned the schematics for both boards are already done, I can move straight into component placement and routing as soon as I receive the files and target dimensions. I'd be happy to jump on a quick call to align on expectations before we start. Looking forward to working together. Best regards, M Khales Please fill free to contact me for a previous interview .

I have good experience and i can do this task for you. I will use OrCAD and provide you the quality deliverables and the first time right designs In my 25 years of experience as an electrical engineer specializing in FPGA and microcontroller designs, I have gained invaluable knowledge about designing complicated hardware systems like yours. Specifically, I have developed a strong skillset in PCB layout and assembly using platforms like OrCAD which guarantees efficiency. My past work heavily involved signal and power integrity management, similar to the task at hand where you require meticulous isolation and safety between different voltage lines. Additionally, my experience with complex PCB design aligns well with your need for a compact form factor integrated in a standard wall switch enclosure. Over the years, I’ve honed my understanding of component placement and routing to optimize spatial utilization without compromising on reliability. This know-how will be critical in achieving your desired outcome without sacrificing any functionality.
