Key benefits


KORU enables 60 fps graphics performance on a Cortex M4 microcontroller. The system can boot in less than 500 ms.


The system is incredibly efficient, taking only 128 kB of RAM and able to sleep 98% of the time while updating a clock every second. The sleep-update-sleep cycle in less than 20 ms.


Our widgets are the functional building blocks of the user interfaces. Each widget is complete with rich set of animations and interactions. With more than 60 widgets we can build most interfaces, this saves time and ensures consistency.
