Interfacing With External Hardware
3.1
Connecting to a LaunchPad
The BoosterPack is ready to connect to any LaunchPad out of the box.
Figure 20
shows the correct
orientation of the BoosterPack on the LaunchPad.
CAUTION
The connectors should be aligned carefully as misalignment could cause
permanent damage to the BoosterPack.

3.2
Connecting a Motor or Other Peripherals
The Boosterpack provides two standard 100 mil spacing female receptacles to interface two unipolar
stepper motors or other peripherals such as relays, solenoids, or LEDs.
Each receptacle provides a six-pin interface. Four pins are dedicated to the outputs of the ULN2003A and
CSD17571Q2 to drive the peripheral, and two pins are connected to the motor supply that is connected to
the board. These two VCC pins allow for connection to both 5-pin and 6-pin type Unipolar stepper motors.
Figure 21
shows two 5-pin unipolar motors connected to the BoosterPack.
