If needed, the enable line can be tied to the 5 volts B+, the motor can
still be controlled with the 2 direction input lines.
For motor speed control, Pulse Width Modulation (PWM) is fully
possible with the D200. The PWM signal is usually applied at the EN
line.
PLEASE NOTE: The only drawback for the D200 is its PWM frequency
response of only 1Khz.
But at its current price, we believe that you're still getting your money's
worth.
About the Voltage Requirements:
Using the D200
D200 Schematic
Join the D200 Group
Most DC motor driver boards are advertised as 12, 24 or even 48 volts.
That means that if you buy a board rated for 24 volts, it won't work on
12 volts and if you try to run it on 48 volts, it might be destroyed.
Not the D200, the D200 can be used on applications where the motor B
+ can be of ANY voltage between 0 and 55 volts. The user will then use
a motor rated just right for the applied voltage. If a motor of a lower
rating than the motor B+ is to be used, the voltage to the motor can be
brought down by pulse width modulation.
Besides the Motor B+, the D200 requires a regulated 5 Volt supply for 2
reasons:
1) For the on board digital circuitry. We figured this should pose no
problem, since all digital and microcontroller circuits, which we
believe, will be used in conjunction with the D200, are powered by a
regulated 5 Volt supply.
2) The on board DC-DC converter. This circuitry generates 3
independent 10 volt supplies for the purpose of supplying the
MOSFET's gates with 10 volts no matter what the motor B+ is at in the
range of 0 to 55 volts.

So you can, just by example: Safely power a 6 volt DC motor at 10
amps, without worrying about biasing the MOSFETs at 10 volts, since
that is taken care of by the on board circuitry, powered by the 5 volt
supply that you have to have anyways to power your other digital or
microcontroller boards.
