Getting Started
3.3
Connecting the Hardware
1. Plug the Stepper Motor BoosterPack onto the LaunchPad as shown in
The terminal block
headers should be oriented towards the USB connector.
2. Connect your stepper motor to the
terminal block header J5
. The motor should have two windings,
each with a + and a – termination. Connect one winding to A1/A2 and the other to B1/B2 (polarity does
not matter). For questions on the motor wire coloring coding, please see the motor’s datasheet.
3. Connect the power supply that will power the Stepper Motor BoosterPack’s DRV8711 and Drive Stage
to the terminal block header J6. The connections have been labeled VM and GND. For full
performance, ensure you can supply as much current as your motor may demand. The Stepper Motor
BoosterPack has a designed operating range from 8.2–52 V up to 4.5 A continuous for each H-Bridge.
WARNING
At high currents the drive stage can increase to high temperatures
4. Enable the power supply
5. Enable your controller and spin the motor. The BOOST-DRV8711 Stepper Motor BoosterPack
combined with a TI LaunchPad provides a complete stepper motor evaluation platform. With the MSP-
EXP430G2 LaunchPad and a MSP430G2553 you can take full advantage of TI's
pre-written stepper
motor control application (see
for additional details).
