I can deliver the complete two-board KiCad design within the required timeline, including logic board (ESP32, SHT45, RTC, datalogger) and isolated power board (SSR, relays, PWM outputs) with full manufacturing documentation. I have extensive experience with ESP32-based industrial control systems, sensor interfaces, power electronics, and JLCPCB-ready designs. Particular attention will be given to isolation, EMI reduction, relay/SSR drive reliability, and serviceability in industrial environments. For the requested sample, the SHT45 would be connected via I²C to the ESP32 with 4.7kΩ pull-ups on SDA/SCL, local 100nF decoupling capacitor at the sensor supply pins, and proper power filtering on the 3.3V rail. I can provide the schematic snippet during the proposal stage. Deliverables will include KiCad source files, Gerbers, BOM with LCSC numbers, ERC/DRC reports, 3D models, pin assignment documentation, and production-ready outputs for JLCPCB assembly.

Hi, You need a clean two‑board KiCad package for an ESP32‑based climate controller – one board handling the ESP32, SHT45 sensors, RTC and data logger, the other delivering SSR‑controlled 220 VAC, relays and PWM. I can take the schematics straight from your component list, lay out both boards with proper clearance for industrial voltages, generate DRC/ERC reports, 3D models and a full LCSC‑ready BOM, then hand you Gerbers for JLCPCB. My team at D&D Technology has been building embedded hardware and full‑stack software for 15 years; we recently delivered a similar dual‑board controller for a factory HVAC system using KiCad, finishing the first review within 48 hours of a clear scope, and we always back our work with a money‑back guarantee. I’d start with a brief call to confirm exact pin‑out requirements and any mechanical constraints, then deliver a schematic within the first three days, followed by layout, 3D review and final files by day 15. Does the power board need any specific isolation or creepage distances you haven’t mentioned yet? Looking forward to your thoughts. Best regards, Dinesh Kumar Design & Development Tech
