-        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).
+        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).
         When running the NSH configuration (a full up application), there is still more than 9KB or SRAM available:
