Using the dual MC33926 motor driver shield with an Arduino (Arduino powered by shield).
It is also possible to power your Arduino directly from the motor shield, as shown in the diagram above,
which eliminates the need for a separate Arduino power supply. When the
ARDVIN=VOUT
shorting
block is in place, the shield’s reverse-protected input power, VOUT, is connected to the Arduino’s
VIN pin. (When power is connected properly, VOUT is essentially the same as the shield’s VIN.) The
Arduino’s power jack must remain disconnected at all times in this configuration.
