Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max
Super simple to use
Works with just about any brushed DC motor.
You can set the current limiting with an removable external resistor Rlim
Crank up your robotics with powerful Adafruit DRV8871 motor driver breakout board. This motor driver has a lot of great specs that make it useful for a wide variety of mechatronics. 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.
Using it is super simple. Connect your motor to the OUT terminal block. Power the board with 6.5-45VDC power on VMotor and provide the H-bridge input control on IN1 and IN2. You can even PWM the inputs and the driver chip will do the right thing.
You can set the current limiting with an external resistor Rlim. We solder in a 30K resistor by default for a ~2A current limit, however you can remove this resistor and/or solder a resistor over it to change the resistance and change the limit.
