 Serial Console
 ==============
 
+As with most NuttX configurations, the NuTiny-SKD-NUC120 configurations
+depend on having a serial console to interact with the software.  The
+NuTiny-SDK-NUC120, however, has not on-board RS-232 drivers so will be
+necessary to connect the NuTiny-SDK-NUC120 UART pins to an external
+RS-232 driver board or TTL-to-Serial USB adaptor.
+
 By default UART1 is used as the serial console on these boards.  NUC120LE3AN
 is provided as an LQFP48 package and, for this case, the UART1 RX signal
 (RXD1) is on PB.4, pin 8, and the TX signal (TXD1) is on PB.5, pin 9.
