@amelectronics

Hi, I reviewed your project requirements and understand the scope of schematic and PCB changes needed in KiCad. I’ve worked on ESP32-based control boards involving mains power, relay switching, Ethernet (W5500), and EMI-safe layouts. The additions like encapsulated mains PSU, RESOL VBus UART interface, pump PWM drivers/feedback, OLED, and manual/off/auto relay switching are all clear. I’ll also verify creepage/clearance for mains sections, MOV/snubber protection, and ensure clean integration with the ESP32-C6 devkit and Zigbee antenna. I can update both schematic and layout while maintaining reliability and manufacturability.

@cpp2048

Although PCB design looks good, but for safety reason ths board needs a redesign at least couple of section. Some of the creepage distances are too poor. So my suggestion to you is, get this board redesigned to meet your current requirement and to enhance the safety margin and reliability. There are couple of small mistakes in schematic design which need addressing, because that could become the point of failure. 2-3 things are major concerns and critical for vulnerability.

Hi, I would recommend using IRM-05-5 from meanwell to provide 5V from AC mains. It is recommended to use line filter alongwith MOV protection. I would also recommend isolating RS-485. Its a bit costly but keeps communications clean. To save GPIOs, we can use PCF8575 as PWM driver. I will set custom Design Rules in KiCAD to ensure creepage and clearance criteria is met. Do you want basic or functional isolation for this? Let discuss this in detail. Thanks

@yaroslavmark

Hi, I have reviewed the project requirements and I have experience redesigning ESP32-based control boards, including mains power integration, relay protection, sensor interfaces, and industrial IoT hardware. I have designed 50+ PCB projects using KiCad/Altium, including 4-layer boards with AC/DC power supplies, RS-485/UART interfaces, PWM motor drivers, and production-ready BOM/Gerber files. Approach: ✅ I will first review the existing KiCad schematic and PCB files, identify design issues, and update the architecture for the new mains-powered ESP32 controller. ✅ I will integrate the encapsulated mains PSU, MOV-based mains and relay protection, and ensure proper isolation, creepage, clearance, and safety layout practices. ✅ I will add the RESOL VBus-to-UART interface, 4-channel pump PWM driver circuitry, and SPI/I2C OLED display support while removing the Raspberry Pi footprint. ✅ I will complete PCB layout updates, perform ERC/DRC checks, and provide revised KiCad source files with manufacturing-ready documentation. Best, Yaroslav

@tetianam8

⭐⭐⭐⭐⭐ I've read through your requirements carefully, and this is exactly the type of KiCad revision project I enjoy—updating an existing design rather than starting from scratch. The requested changes are clear: replacing the external 24V-derived supply with an encapsulated mains PSU, integrating the RESOL VBus-to-UART interface and four PWM pump drivers from your proven schematics, adding an OLED interface, removing the Raspberry Pi footprint, and incorporating MOV protection on both the mains input and relay outputs. I'll also update the PCB layout to accommodate these changes while maintaining proper creepage, clearance, and a clean, manufacturable design. Milestones: Review existing KiCad project & reference schematics Schematic updates PCB layout revision & routing ERC/DRC verification and final files One question before we begin: do you already have preferred part numbers for the encapsulated AC-DC PSU and OLED module, or should I recommend components that fit the existing board constraints? I'd be happy to start immediately and provide regular progress updates as the design evolves.

Hi, If you need more than Gerber files — if you need working assembled boards on your desk — I am a strong fit. I combine 14+ years of PCB design and firmware work with real manufacturing experience inside a Shenzhen PCB factory. I previously worked at READA PCB Technology in Shenzhen as a PCB designer, production manager, and manufacturing coordinator. I know how designs are quoted, fabricated, assembled, inspected, and shipped — so I can manage your project from schematic to tested units without losing time between separate vendors. What I can deliver: • Schematic and PCB layout (Altium, KiCAD, or Eagle) • DFM/DFA review before release to production • PCB fabrication and PCBA coordination • Component sourcing and BoM optimization • Functional testing against your test specification • Fast shipping for prototype and small-batch runs I also work with JLCPCB, PCBWay, and Seeed Studio when clients prefer those channels, but my advantage is firsthand factory knowledge from READA and a single point of contact through design, assembly, and debug. I have designed and manufactured IoT controllers, LTE HATs, OBD boards, and mixed-signal embedded products. I can share relevant examples once we connect. Tell me your target quantity, timeline, and whether components are consigned or fully sourced — I will reply with a clear path to first article. Best regards, Ting

Hi, The biggest risk in this project is not updating the existing KiCad design—it is integrating the new power, communication, and control circuitry while maintaining reliable operation, proper mains isolation, and a manufacturable PCB layout that meets electrical safety requirements. I have 30 years of experience in PCB design, ESP32-based embedded systems, power electronics, Ethernet integration, industrial control hardware, and KiCad development. I have successfully redesigned and optimized numerous embedded control boards for prototype and production applications. For this project, I would focus on: 1. Updating the schematic and PCB layout to integrate the encapsulated mains PSU, W5500 Ethernet, OLED display, and RESOL VBus interface. 2. Optimizing the relay drivers, PWM outputs, protection circuitry, creepage/clearance, and overall PCB layout for safe and reliable operation. 3. Delivering a clean, production-ready KiCad project with proper DRC/ERC validation and manufacturable outputs. ✅ A Few Quick Questions: 1. Are all the reference schematics for the VBus and PWM drivers included? 2. Do you already have a preferred encapsulated AC-DC power module? If you message me, I can review the existing KiCad files and outline the most practical hardware revision strategy for a reliable and production-ready design. Best regards, Prat PCB Must Innovations
