    Ka-Ro CoM scalability

    Often, devices are required in different performance and price classes. This is where Ka-Ro’s TX standard comes into its own. With one single hardware design embedded engineers can produce a range of pin- and software-compatible products. Ka-Ro introduced the TX CoM standard over six years ago. Until today, the Ka-Ro Starter Kit V has served as the unchanged development environment for all Ka-Ro TX modules underlining Ka-Ro’s long-term product and family strategy. All the TX modules can be used on the Starter Kit V which enables great scalability and flexibility.

    Reduce to the max the Ka-Ro product philosophy

    The philosophy behind Ka-Ro’s TX CoM family is to reduce a CoM down to the absolute minimum of components. In doing so, application designers and engineers using Ka-Ro CoMs can achieve maximum flexibility. Ka-Ro TX CoM modules solely feature the processor plus memory and the power supply. Any additional functions can be added to the base board.


    This focus on CoMs with a minimum number of components is on the one hand the key to very competitive pricing, on the other hand it enables Ka-Ro to ensure long-term availability. While processor manufacturers like NXP offer a long-term availability of 10 to 15 years, this must also apply to any further components integrated onto a module or these must be available via second sourcing and without any necessary software alterations.

    If these components are integrated on a module, as is the case with many other manufacturers, this long-term availability is endangered, or from right from the start not possible to guarantee.
