4 Hardware and Software Overview
4.1 LEDs, Switches, and Jumpers
There are LED indicators on both the LAUNCHXL-F280049C and DRV8316xEVM when power is provided.
The LAUNCHXL-F280049 LaunchPad LEDs power up when the Micro-USB cable is plugged in and their
functionalities are not modified upon powering the board.
The DRV8316xEVM has four status LEDs implemented on the board. By default, the VM and 3.3-VBK LEDs
will light up when the board is powered and the MCU LED (tied to GPIO59) can be used for debugging and
validation.
