{{bloc-etroit|text=The DRV8833 can actively limit the current through the motors by using a fixed-frequency PWM current regulation (current chopping). By default, this carrier board connects the current sense pins to ground, disabling the current limiting feature. To enable current limiting, you can use a knife to cut the break points on the back of the board and then solder some appropriate current sense resistors to the unpopulated pads on the front, as indicated in the image below. The pads are sized for 1206 surface-mount resistors. Refer to the DRV8833 datasheet for information on how the resistor value determines the chopping current.}}
