    Bekonix

    Bekonix

    Bekonix

    Our goal is really to help you create smart, connected projects and products from concept to final design. So that means everything from putting together the hardware components, the firmware, the behaviors and even the end-user mobile app to control it. The Bekonix Platform lets you try out ideas in minutes that would take days or weeks the traditional way. What’s more, since no programming is required, motivated creatives can jump in and not just talk about making a smart, connected product but invent it in real time. Unlike many prototyping tools out there, Bekonix is built for the next level of manufacturing. Real code, real connections. If you need larger volumes to reduce hardware costs, Bekonix can easily migrate with your needs.
