+  The Nucleo F401RE and a single user LED, LD2.  LD2 is the green LED
+  connected to Arduino signal D13 corresponding to MCU I/O PA5 (pin 21) or
+  PB13 (pin 34) depending on the STM32target.
+
+    - When the I/O is HIGH value, the LED is on.
+    - When the I/O is LOW, the LED is off.
+
+  These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+  defined.  In that case, the usage by the board port is defined in
+  include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related
+  events as follows when the red LED (PE24) is available:
