+ * Mightyboard Rev.E pin assignments
+ * also works for Rev D boards. It's all rev E despite what the silk screen says
+ */
+
+/**
+ * Rev B  2 JAN 2017
+ *
+ *  Added pin definitions for:
+ *    M3, M4 & M5 spindle control commands
+ *    case light
+ *
+ *  Corrected pin assignment for EX2_HEAT_PIN pin. Changed it from 9 to 11.  The port
+ *  number (B5) agrees with the schematic but B5 is assigned to logical pin 11.
