Hello there, I’ve read your Toshiba AC ESP32-C3 Industrial Controller brief and I’m confident I can deliver a robust, production-ready gateway that bridges Toshiba AB, Modbus RTU, and local 0-10 V I/O. I will design a DIN-rail mounted, CE-compliant board using the ESP32-C3 with galvanic isolation on the AB-UART path, a hardened RS-485 Modbus master, and a clean 0-10 V output stage. My approach follows Screaming Architecture: a modular firmware stack in C/C++, precise UART ring buffers, stable Modbus polling, and a small, maintainable codebase with clear interfaces and extensive fault handling. The hardware will use the Mean Well IRM-10-5, with proper creepage/clearance per IEC 60664-1, fused protection, MOV, and isolation between primary and secondary. The web dashboard will be a lightweight React/Vite app, hosted locally from LittleFS, with OTA updates and Home Assistant auto-discovery for easy integration. Deliverables include complete source code, manufacturing docs, and IP transfer on final payment. The next step would be a project kickoff within 1-2 weeks, followed by a design review, prototype, and field testing plan. For the project I’d like to confirm a few essential points to tailor the design. 1) CE / Safety: How will you ensure creepage and clearance compliance for a 230 V AC PCB according to IEC 60664-1? 2) Analog Design: Which SPI-based ADC would you select to keep 0–10 V inputs stable during Wi-Fi transmission, and why? 3) RS-485 Robustness: How will you de

@yaroslavmark

✅ Okay, I got what you want exactly. I am a senior embedded systems and industrial electronics engineer with over 10 years of experience, providing ESP32 firmware development, industrial PCB design, CE-compliant power electronics, Modbus/RS-485 communication, and embedded web interfaces. In my opinion, this controller should be designed as a noise-resilient industrial system from day one, not a hobby ESP32 board adapted later. I would focus on strict power domain separation, robust analog front-ends, and a clean firmware architecture so the device remains stable under Wi-Fi load, EMI, and long-term field operation. This project is very similar to my previous works. I’ve designed DIN-rail HVAC gateways using ESP32 and STM32 with isolated UARTs, RS-485 Modbus masters polling 8–12 slave modules, and 0–10 V I/O using external SPI ADCs with dedicated analog ground planes. I’ve also delivered CE-ready PCBs with IRM-series PSUs, validated creepage/clearance, and shipped units with captive-portal provisioning and MQTT auto-discovery for Home Assistant. ✅ So, I will divide your project like following: ⚡ Hardware architecture, safety review, and component selection ⚡ Schematic & PCB layout with isolation, analog stability, and EMI control ⚡ ESP32-C3 firmware (AB protocol, Modbus RTU master, MQTT, OTA) ⚡ React/Vite single-file dashboard integration and provisioning flow ⚡ Manufacturing package and documentation handover Best regards.
