+// Notes
+//
+// - The pins mentionned Px_y_ALTz are alternative possibilities which use other
+//   HW peripheral instances. You can use them the same way as any other "normal"
+//   pin (i.e. PwmOut pwm(PA_7_ALT0);). These pins are not displayed on the board
+//   pinout image on mbed.org.
+//
+// - The pins which are connected to other components present on the board have
+//   the comment "Connected to xxx". The pin function may not work properly in this
+//   case. These pins may not be displayed on the board pinout image on mbed.org.
+//   Please read the board reference manual and schematic for more information.
