Product description
Small breakout board for Texas Instruments DRV8871 Single channel DC motor driver. The driver is controlled with two PWM signals and will drive a connected DC motor in both directions. The inputs will accept both a static DC voltage to run the motor at 100% or PWM signals to vary the speed. When both inputs are low, the motor is disconnected from the driver outputs and is free to spin (coast). When both inputs are high, the motor will be braked and resist rotation.
The driver also contains a clever current limiting that can be programmed with a single resistor. Other protection features are undervoltage lockout, overcurrent protection and thermal shutdown.
In short, a very capable, low-cost, easy-to-use and reliable motor controller for all small brushed DC motors.
