3-Phase BL0906 Energy Metering Schematic

@ahmedy607

Hello, I’ve read through the project details, and this is exactly the type of PCB design work I specialize in. I have experience with compact multi-layer boards, critical placement and routing, DFM, and production-ready manufacturing files. You can check my portfolio for similar projects. I’m ready to start and deliver a clean, reliable layout while respecting all mechanical and component constraints. Best regards, Ahmed Yahia

I can design the complete production-ready schematic for your 3-phase BL0906 energy-metering system with STM32F103CBT6 and SPI interface to ESP32. I’ll handle CT/voltage-output sensor selection, ZMPT101B inputs, phase-wise passive filtering and protection, calibration provisions, fault monitoring, and proper signal conditioning. You’ll receive the editable KiCad project, PDF schematic, sourcing-friendly annotated BOM, and concise design notes covering CT burden, jumper configuration, filter calculations, and calibration. Lets discussion about work in details.

Dear Client, I’m interested in designing the **three-phase BL0906 + STM32F103CBT6 energy-meter interface**. I have **15+ years of embedded electronics and PCB design experience**, including metering, ADC/sensor interfaces, STM32 and SPI-based systems. I can provide: * Production-ready **KiCad schematic** with BL0906, STM32F103CBT6 and fixed SPI interface to ESP32. * Three-phase voltage/current sensing architecture. * Jumper-selectable **CT or voltage-output current sensor** input. * ZMPT101B voltage-sensing interface. * Passive filtering and protection for each phase, designed around 50/60 Hz measurement requirements. * CT burden and input-scaling calculations. * Jumper selection logic and protection. * STM32 processing for RMS voltage/current, active power, energy, frequency and fault/status registers. * Calibration provisions for voltage, current and power accuracy. * Design notes explaining component selection and allowing future sensor-value changes. * ERC/DRC review and documentation suitable for prototype/production development. I would pay particular attention to **mains isolation, creepage/clearance, transient protection, CT burden safety and analog noise**, since these are critical in a three-phase energy-meter design. I can work in **KiCad** and deliver the editable project along with the schematic PDF and BOM. **Best regards,** **Subhash Suman** Embedded & Electronics Engineer | STM32 | Energy Metering | PCB Design | 15+ Years Experience
