Hello, I can design your PCB and prepare it for direct manufacturing at **JLCPCB** using **EasyEDA**. For this project I will: • Create the schematic integrating **Ai-Thinker VC-02** with **CH32V003F4P6** via UART • Design the 5V → 3.3V power stage using **AMS1117-3.3** with proper filtering and decoupling • Implement **8 digital inputs** and **8 relay outputs** driven through **ULN2803ADWR** • Arrange the **eight relay outputs in a single block** for clean wiring and minimal trace lengths • Add all required connectors: input header, programming ports, microphone, speaker, and 5V power input The layout will follow good design practices: • short and wide power traces • decoupling capacitors close to the MCU and VC-02 • separation of **audio lines from relay switching noise** Deliverables will include: • Complete EasyEDA schematic and PCB layout • Gerber files ready for fabrication • Exportable BOM with part numbers and packages Best regards, Ahmed

I’m an embedded systems and PCB designer with experience in EasyEDA, microcontroller boards, relay control circuits, and voice modules. I can design a clean, production-ready PCB integrating the Ai-Thinker VC-02 voice recognition module with the CH32V003F4P6 MCU, ready for direct ordering from JLCPCB. Solution approach: -Create a well-structured schematic with correct footprints and clear net labeling. -Design the PCB layout with all eight relays grouped together for tidy wiring and minimal trace length. -Implement proper power routing (5V → AMS1117-3.3V) with short, wide power traces and close decoupling for the VC-02 and MCU. -Keep audio signal lines isolated from relay coil noise for reliable voice operation. -Provide all connectors: 9-pin input block, VC-02 programming header, CH32 programming header, speaker, microphone, and 5V power input. Deliverables: -Complete EasyEDA project (schematic + PCB) -Manufacturing Gerber files ready for JLCPCB -Exportable BOM with part numbers and packages -Organized layout suitable for reliable fabrication and assembly The final design will be clean, electrically robust, and ready for manufacturing without additional redesign. Best regards

Hello, I am an Embedded Systems Engineer with extensive experience in microcontroller-based designs and PCB development. I can design this PCB for you and deliver a fully manufacturable EasyEDA project ready for JLCPCB. I have solid experience designing embedded control boards with MCUs, relay drivers, and mixed-signal sections (kindly review my portfolio section). I’ll ensure the board follows proper layout practices for reliability and low noise. Looking forward to working on this. Best regards, Hossam Mamdouh Embedded Systems Engineer

@djalltra

Hi, I can handle this PCB design for you. The specs are clear: VC-02 voice module paired with CH32V003 MCU, eight relay outputs driven by ULN2803, onboard 5V to 3.3V conversion, and all required connectors. I'll lay it out in EasyEDA for JLCPCB fabrication. The schematic will use correct footprints and clean net labelling. On the PCB, I'll group the eight sugar-cube relays in a block for neat wiring and keep trace lengths minimal. Power traces get adequate width, decoupling caps sit tight to the VC-02 and MCU, and audio lines route away from relay noise—standard practice. You'll get both programming headers (VC-02: TX, RX, VCC, GND; CH32V003: PD1, VCC, GND), speaker and microphone connectors, the 8-input block with common GND return, and the 5V power inlet. Everything you specified. Deliverables: complete EasyEDA project files, ready-to-manufacture Gerbers, and exportable BOM with part numbers and packages. No revisions needed just send to fab. Let me know if you want to move forward. Terlumun

Hello, I'm Nabil electronics and embedded systems engineer I have experience C Embedded and PCB design using EasyEDA kindly message me to discuss more about requirements and I would start immediately best regards, Nabil

@simranjotk8

Hi, I am an electronics engineer specializing in mixed-signal PCB layout and embedded systems. I have reviewed your project and can deliver a "first-time-right" EasyEDA design optimized for JLCPCB fabrication. Why choose my design? Noise Isolation: I will implement strict physical separation between the relay coil switching noise and the sensitive VC-02 audio lines to ensure crystal-clear voice recognition. Thermal & Power Management: I'll use wide power traces for the $5\text{V}$ rail and properly placed decoupling capacitors for the AMS1117-3.3 to prevent MCU resets during relay activation. Protection: I will correctly bias the ULN2803ADWR COM pin to handle inductive flyback from the 8 sugar cube relays. Manufacturing Ready: You will receive a complete package including Gerbers, Drill files, and a verified LCSC BOM for seamless SMT assembly. I am ready to start immediately and can provide a 3D render to verify component clearances before you place your order. Best regards, Simranjot
