PWM Control Mode

The PWM DC motor control is implemented by manipulating two digital IO pins and two PWM pins. As
illustrated in the diagram above (Figure 5), Pin 4,7 (7,8 for old Romeo version) are motor direction control
pins, Pin 5,6 (6,9 for old Romeo version) are motor speed control pins.
For previous Romeo board, the pins used to control the motor is Pin 7,8 (Direction), Pin 6,9 (Speed). You
can find the information at the right side of the Motor Control Pin Jumpers.
