ESP32 S3 Home Automation Relay

@amelectronics

Hi, I’d be glad to help with your ESP32-S3 audio/IoT prototype. I have hands-on experience designing compact embedded hardware with ESP32, battery management, USB-C power, audio circuits, SPI displays, NFC/RFID integration, and custom PCB layouts. I can deliver a clean, production-ready KiCad schematic and PCB with proper power-path management, low-noise audio routing, optimized component placement, and complete manufacturing files, including Gerbers, BOM, and pick-and-place data. My goal is to create a reliable, easy-to-manufacture design that is ready for prototype assembly and future production. I’m confident I can deliver this project and would be happy to discuss your requirements and timeline to get started.

I design custom ESP32-S3 relay boards for real-world retrofit—AC isolation, compact PCB, relay+triac mix, and field-ready for MQTT. For your 8-channel layout: 6 triac zones (BTA06/BT136), 2 relay, all with opto-isolation, per your spec. I never use capacitive dropper—only proper isolated flyback AC-DC (HLK, MORNSUN or equivalent), 5V/3.3V rails, safe for 24/7 India mains. You get: all original KiCad project files (sch, brd, BOM, Gerber, PnP). I size the PCB for Indian modular boxes (typically 47-51mm depth, 80x50mm face or smaller). All safety features: MOV, snubber, fuse, clear channels between AC and low-voltage, and no LED ghosting on triac outputs. I’ve shipped similar boards for building retrofit jobs—industrial control, lighting, fan+socket mix, always with test points and expansion headers. Firmware flashing header (UART), IR, I2C spares, all included. Do you have any part constraints, or will you accept easy-to-source, common SMD parts for assembly? Pradeep

As an experienced mobile app developer with a strong background in home automation and working with ESP boards like the ESP32-S3, I feel that I'm uniquely suited for this project. I understand the need for a compact, reliable solution in home automation systems, and have successfully implemented similar solutions before. I've also worked on several projects that involve voice commands and remote control setup in such systems. In terms of electricals specifically, I have experience working with relay modules and designing PCB layouts. I am familiar with microcontrollers and MQTT based firmware development, which will be crucial to the success of your project since reliability is a priority. Additionally, my previous experiences include building mobile apps for remote control interfaces, making me skilled in interfacing hardware with software. Designing for a 230V AC input system is not new to me as I have developed smart home solutions targeting different countries. India's electrical system included.I understand your specific needs for 24/7 continuous operation and the importance of good WiFi signal strength. Besides, since PCB real-estate is at premium here,I can design a compact solution that ensures all your requirements in terms of size are met. My commitment to delivering work that aligns well with my client's vision while upholding utmost safety standards make me the best fit for your project.I look forward to collaborating with you on this meaningful ven

I've shipped production IoT systems like this before, including a solar-powered ESP32 water vending machine for a remote desert community that ran entirely offline with RFID access. That project needed precise relay control, robust firmware, and zero connectivity — all things that apply directly to your home automation relay. I handle the full stack from firmware to PCB design and 3D enclosure, and I ship working prototypes. I can ship your project in my lab. If you want a relay controller that's reliable and built to last, I can deliver it without the usual back-and-forth. Let's get it done.

Hello, Your project is a well-defined embedded hardware design that requires careful attention to safety, reliability, and manufacturability. We can design a compact **ESP32-S3 8-channel smart switch PCB** optimized for Indian 230V AC installations and continuous 24/7 operation. The design will include an isolated AC-DC power supply, **6 opto-isolated TRIAC outputs** for lighting, **2 mechanical relay outputs** for heavier loads, wall switch inputs, UART programming header, status LEDs, reset/boot access, and optional I2C and IR expansion headers. We'll implement proper fuse protection, MOV surge protection, isolation clearances, snubber circuits where required, and PCB layout practices suitable for production. The PCB will be optimized for a compact footprint while maintaining good Wi-Fi performance by preserving the ESP32-S3 antenna clearance. Component selection will prioritize parts that are readily available for assembly and long-term maintenance. Final deliverables will include **KiCad project files, schematics, Gerbers, BOM, Pick-and-Place files**, and production-ready documentation. We'll also support prototype PCBA manufacturing and ensure the boards are ready for firmware flashing and functional testing. Rahul Hazarika Brahmaputra Tech
