5 Hardware Setup
The hardware required to run the motor control is the LAUNCHXL-F280049C LaunchPad development kit, the
DRV8316xEVM, a Micro-USB cable, and a power supply with a DC output from 8-V to 32-V. Follow these steps
to start up the DRV8316xEVM:
1. Mate the DRV8316xEVM board to the top half of the LAUNCHXL-F280049C LaunchPad development kit
(mates to J1/J3 and J2/J4 of the LaunchPad, as in
). Ensure resistor R13 is DNP on the bottom of
board to separate buck voltage from the USB power supply voltage.
2. Connect the three phases from the brushless DC motor to the three-pin connector J4 on DRV8316xEVM.
Phases OUTA, OUTB, and OUTC are labeled in white silkscreen on the PCB top layer. If using a sensored
algorithm on the LaunchPad development kit, connect the Hall sensor to the five-pin connector J7.
3. Connect the DC power supply to header J5, ensuring the correct polarity of VBAT and PGND is applied.
4. Connect a Micro-USB cable to the LaunchPad development kit and computer.
5. Turn on the power supply and power up the PCB.
6. If using the DRV8316xEVM with an external microcontroller, make the logic-level connections needed on
the male headers on the top of the board or female connectors on the bottom side of the board. The signal
names are labeled on the bottom side of the board for convenience as
shows.
