         As of this writing, more device drivers are needed to make this a more complete port.

-        For a full-featured RTOS such as NuttX, providing support in a usable and meaningful way within the tiny memories of the NUC120 demonstrates the scalability of NuttX (128KB FLASH and 16KB of SRAM in a 48-pin package).
