/**
 * 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.
