3 Quick Start Guide
The DRV8311HEVM requires a power supply with a recommended operating range from 3-V to 20-V. To setup
and power the EVM, follow the sequence below:
1. Connect the power supply ground to the GND of the 2-pin power connector J3 and the power supply positive
terminal to the VM pin of J3. Ensure jumpers JP1, JP2, and JP3 of the LAUNCHXL-F280049C are populated
to ensure that 3.3 V and 5 V are powered from the LaunchPad.
2. Connect the motor phases to OUTA, OUTB, and OUTC in the correct order. For sensored applications,
connect the Hall sensors to the appropriate locations on the 5-pin connector J4 as shown in Figure 4-2 .
Select 3V3 or 5V on jumper J6 to choose the Hall power source voltage.
3. Mate the DRV8311HEVM onto the top half of the LAUNCHXL-F280049C (LaunchPad Headers J1/J3 and
J2/J4) as shown in Figure 4-3 . The motor and power connectors should face the same direction as the
Micro-USB connector on the LaunchPad.
4. Connect a Micro-USB cable from the computer into the Micro USB connector on the top of the LAUNCHXL-
F280049C.
5. Power on the DRV8311HEVM.
