With the exception of the pins labeled “D2 1=2” and “SF 1=2”, all of the through-holes not highlighted in the
above diagram are only relevant when using this driver as an Arduino shield. The “D2 1=2” and “SF 1=2” pins
are explained in the “Pinout” portion of
, but they will not be needed in typical applications and can
generally be ignored.
4.b. Board Connections
Using the dual MC33926 motor driver shield with a microcontroller (gray connections are
optional).
The above diagram shows the minimum connections typically required to interface this motor driver with a
microcontroller. Note that D2 is internally pulled low, which disables the motor outputs; it must either be
connected to an I/O line (for dynamic control) or soldered to the neighboring VDD pin to enable the drivers. Only
two pins are required per motor: direction control with MxDIR and speed control with MxPWM.

The following table explains the board pins in detail. See the
(1MB pdf) for even more detailed information about these pins.
