My hardware design includes a Printed circuit board design with customized requirements. I provide complete PCB layout design, prototype PCB board manufacturing, testing of PCB board with advanced tools, and on-demand I provide small-scale production of the hardware /PCB. Price will be negotiable on hardware design and development. My PCB design features include - ► Multilayer PCB design. ► Both rigid and rigid-flex design. ► Provide BOM with the most available component list. ► Provide Gerber and ECAD files for manufacturing. ► Support prototype and small-scale production (PCB). My last project is " LORAWAN BASED ENERGY METER EXTENSION", where I have to measure the Phase voltage, Line voltage, phase current, Line current, Total energy, power factor and send them to the TTN server using LORAWAN based prototype node device and Dragino gateway. The device was successfully worked and installed in the industry environment. You can see details of its working in my portfolio. My goal is to provide the best quality services at an affordable price within a reasonable timeframe. Please visit my website for more details - www. bit-plexlab.com
