NavStik comes with a huge 16-Mb Flash Memory for storing all the configuration, calibration and other platform specific data in non-volatile memory. This helps in separation of the platform-specific data from the rest of firmware, for better portability of user applications across hardware. It also helps in freeing up the precious processor flash of platform-specific data.
All interface boards for NavStik provide a slot for micro-SD card for data-logging. A driver for FAT filesystem is available in the set of free and open-source drivers at navstik.org.
