Interfacing Drv8316Xevm And Launchxl-F280049C Launchpad - Texas Instruments DRV8316 EVM Series User Manual

Hardware and Software Overview

4.4 Interfacing DRV8316xEVM and LAUNCHXL-F280049C LaunchPad

The DRV8316xEVM has 40 pins with different functions. These pins are interfaced with the LAUNCHXL-
F280049C LaunchPad development kit and are mapped appropriately to receive the functionalities of the
DRV8316R device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to
J4). Table 4-5 and Table 4-6
