Hi, You can review my portfolio for similar projects, I have experience designing ESP32-based and mains-powered boards, including relay control and production-ready layouts. I can develop the complete schematic and PCB with proper AC-DC power architecture, protection circuits, relay drivers, and ESP32 RF layout considerations. The design will follow good creepage and clearance practices and include all manufacturing files and a documented BOM. Best regards, Ahmed

I’ve shipped over a dozen custom relay controller boards just like this one, each with integrated power supply and clean PCB layout. Your ESP relay board is a straightforward design, and I can move from schematic to a fully tested prototype in a short, focused sprint. I handle the full stack — firmware, PCB layout, and component sourcing — so there’s no back-and-forth between separate engineers. I’ve also built and shipped complete hardware prototypes globally, including solar-powered vending machines and industrial control systems, so your board will be production-ready from the first spin.

Hello, I am a Hardware Design Engineer with experience in ESP32-based designs, power electronics, SMPS circuits, relay control boards, and production-ready PCB development. I can design a compact and reliable PCB integrating an ESP32 module, four 10A relay outputs, and an isolated AC-DC power supply supporting the full 110–220 VAC input range. The design will prioritize electrical safety and manufacturability, including proper creepage and clearance distances, input fusing, MOV surge protection, EMI filtering, relay isolation, and clearly defined mains/low-voltage separation. Special attention will be given to the ESP32 RF section, ensuring antenna keep-out requirements are maintained and high-current or noisy components are positioned to minimize interference. Deliverables will include: • Complete schematic in KiCad or Altium • Production-ready PCB layout • Gerber, drill, and pick-and-place files • Fully annotated BOM with manufacturer part numbers • Design note covering safety features, test points, and design considerations I have worked on embedded control boards, SMPS-based power systems, ESP32 hardware, and industrial control PCBs, allowing me to efficiently deliver a robust design suitable for fabrication and deployment. I can provide an initial schematic/layout draft quickly and support revisions until the design is finalized. Best regards, Anjali

Hi, I can design the compact ESP32 4-relay PCB with onboard 110V–220V AC to DC power supply, relay outputs, status LEDs, and production-ready fabrication files. The best solution is to treat this as a mains-powered safety-critical PCB from the start: select an isolated AC-DC module or proven supply stage, add fuse protection, MOV/TVS surge protection, proper filtering, relay driver circuitry, flyback protection, clearly separated high-voltage and low-voltage zones, adequate creepage/clearance, and an ESP32 antenna keep-out area free from copper and tall components. I’m comfortable with ESP32 PCB design, relay control boards, AC mains input protection, isolated power supplies, KiCad/Altium, creepage/clearance rules, relay driver circuits, BOM preparation, Gerber/drill/pick-and-place generation, and DFM-focused PCB layout. Deliverables will include: * Complete schematic * Compact PCB layout * Gerber and drill files * Pick-and-place file * Annotated BOM with MPNs * Relay/status LED/test point layout * Short design note covering safety separation, fuse/surge protection, and test points I can prepare an initial schematic/layout draft quickly after receiving relay preference, enclosure size, terminal type, and board dimension constraints. Best regards Ankit

I can design a compact ESP32-based 4-relay PCB with an integrated 110–220 V AC to low-voltage power stage, focusing on safety, reliability, and clean layout. The design will ensure proper isolation between mains and logic, with correct creepage/clearance, fuse and surge protection, and a stable regulated supply for the ESP32. The antenna keep-out area will be strictly preserved, and relay drivers will support at least 10 A per channel with LED status indicators. I will optimize the layout for compact size while keeping high-voltage and low-voltage sections clearly separated to ensure safe and robust operation. Deliverables will include schematic, production-ready PCB files (KiCad or Altium), BOM with MPNs, and a short safety/design summary.

I have experience working on ESP32-based control boards, relay driver circuits, AC/DC powered embedded systems, and PCB design workflows in KiCad. For mains-powered boards, I follow isolation, creepage/clearance, fusing, MOV surge protection, and antenna keep-out practices, with final safety review recommended before production.

Hi, I specialize in mains-powered embedded hardware and can handle this end to end. I can deliver this complete — ESP32-WROOM-32, 4× 10A relays with status LEDs, and a safe mains input stage. Pricing depends on the PSU approach: • Certified module (happy to share details in chat) — $30 Approx. 6–7 days. Simpler, pre-certified, recommended. • Discrete flyback (custom transformer) — $60 Approx. 12–14 days. Higher cost, more NRE. Most clients go with the module, same isolation and safety, fraction of the effort. Happy to jump on a quick call to confirm scope. Ready to start immediately.

I am an experienced embedded hardware designer with a strong background in developing safe, mains-powered IoT systems. I understand that for a board integrating high-voltage AC-DC conversion and sensitive ESP32 logic, safety is paramount. My Technical Approach: Safety Standards: I will strictly adhere to IPC-2221 standards for creepage and clearance. I will implement a physical isolation slot between the mains-side power stage and the low-voltage ESP32 logic to ensure maximum protection against electrical arcing. Reliable Hardware: I will incorporate essential surge protection (MOV), proper fusing, and robust relay drive circuits using flyback diodes to protect the ESP32 from inductive spikes. Layout Excellence: I will ensure the antenna keep-out zone is entirely free of copper and tall components to maintain optimal Wi-Fi connectivity. Deliverables: You will receive a clean, annotated schematic in KiCad/Altium, production-ready Gerbers, a detailed BOM with manufacturer part numbers, and a design note summarizing safety test points. I have successfully designed similar hardware for industrial and home automation projects. I am prepared to deliver an initial schematic and layout draft within your required timeframe and am ready to start immediately

Hi, Your project is interesting because it combines ESP32 integration with mains-powered PCB design and production-ready layout requirements. I work with embedded hardware development, PCB design in KiCad, microcontroller integration, and hardware bring-up. I can help create a clean and manufacturable ESP32 + relay control board with attention to layout quality and documentation. For this design I would focus on: • ESP32 integration with proper antenna keep-out and RF-aware placement • 4 relay outputs with driver stage and status indication • Universal AC input (110–220 VAC) with isolated power architecture • Protection considerations including fuse placement, surge protection, creepage and clearance review • Separation of high-voltage and low-voltage sections with accessible test points • Fabrication-ready outputs including schematic, PCB, Gerbers, drill files, pick-and-place, and BOM I have experience with embedded systems, PCB workflows, and integrating microcontrollers with real hardware constraints. Before starting I’d like to confirm: 1. Preferred ESP32 module (WROOM/WROVER/custom) 2. Relay load type (resistive/inductive) 3. Target enclosure dimensions 4. Preferred board manufacturer and layer count I can begin with a schematic and initial placement quickly and iterate based on your feedback. Thanks, Santanu
