@sivom

Hi, Do you have any schematic or circuit diagram of your product that you are going to develop? What all other components involved? Does it operate on any battery? what is the size and voltage? Can we use ESP32 which has both WiFi/BLuetooth in a single module. You want only the following right and not any firmware development? Complete schematic capture and PCB layout Gerber, drill, and pick-and-place files ready for fabrication. A concise BOM with part numbers that have strong supply-chain availability. We can discuss Regards Senthil Chennai

Hi, there. In a recent project, I designed a compact PCB for a wearable device that integrated both Wi-Fi and Bluetooth functionalities, optimizing for size and performance. I implemented a multi-layer design to manage complex routing, ensuring minimal interference between RF sections. One of the challenges was maintaining signal integrity while fitting within strict dimensional constraints, which I addressed by using impedance-controlled traces and strategically placed ground planes. I offer to leverage my experience with advanced simulation tools to predict performance issues early in the design phase, ensuring compliance with industry standards. My unique approach involved utilizing a hybrid design methodology that combined traditional layout techniques with modern simulation practices, which allowed for rapid iteration and refinement. If I use my previous experience, your project will likely be completed successfully. Hope to discuss this in detail. Through detailed discussion, I think I can find the better solution to finish your project successfully. Thank you.

Recently, I worked on the wearable safety device project, where I was involved in hardware design, PCB development, ESP32 integration, sensor interfacing, LoRa communication, GPS integration, power management, and enclosure design. The project required compact PCB layouts, wireless communication reliability, and prototype-to-product development. I would be happy to discuss your preferred wireless module, enclosure constraints, and production goals before starting the design.
