You can set the current limiting with an external resistor Rlim. You can even PWM the inputs and the driver chip will do the right thing. Power the board with 6.5-45VDC power on VMotor and provide the H-bridge input control on IN1 and IN2. Connect your motor to the OUT terminal block. Current limiting/regulation without an inline sense resistor.In particular, the simple resistor-set current limiting and auto-magic PWM support make it super easy to use with just about any brushed DC motor. This motor driver has a lot of great specs that make it useful for a wide variety of mechatronics. Crank up your robotics with powerful Adafruit DRV8871 motor driver breakout board.
