Product philosophy

Product philosophy

Exceptional scalability, comprehensive long-term availability and a wide range of peripheral options are the hallmarks of Ka-Ro's TX standard and have helped the TX series products gain widespread acceptance in a wide range of market segments.

The philosophy of the Ka-Ro TX CoM family is to reduce a CoM to a minimum of components. Application developers and engineers using Ka-Ro CoMs can achieve maximum flexibility. Ka-Ro TX CoM modules only have the processor plus memory and power supply. Additional functions can be added to the base board.

This focus on CoMs with a minimal number of components is on the one hand the key to a very competitive pricing, on the other hand Ka-Ro enables a long-term availability. While processor manufacturers such as NXP offer a long-term availability of 10 to 15 years, this must also apply to all other components that are integrated into a module. If these components are integrated on a module, as is the case with many other manufacturers, this long-term availability is endangered or - from the outset - not guaranteed.
