I have experience working with ESP32, EasyEDA, and GSM modules, and I have designed PCBs integrating these components. I also have an ESP32 and a fully equipped electronics lab where I can assemble and test the circuit. My Approach: I will start by designing a clean schematic in EasyEDA with the ESP32, 12V relay, SIM800 GSM, and regulated power supply. I will include isolation for the relay, proper buck converters, keep-out areas for the antenna, and test points for all power lines. Then I will create the PCB layout, separating high-current and low-signal areas, adding mounting holes, and labeling clearly. After layout, I will do a basic functional test in my lab to ensure everything works before sending the final files. Deliverables: • Complete schematic in EasyEDA • PCB layout files • Gerber files ready for manufacturing • BOM (Bill of Materials) • 3D PCB view • Optional PDF schematic
