DRV8874 Single Brushed DC Motor Driver Carrier

This compact breakout board for TI’s DRV8874 motor driver offers a wide operating voltage range of 4.5 V to 37 V and can continuously deliver 2.1 A to a single bidirectional brushed DC motor. The DRV8874 also features integrated current sensing and regulation, which limits the motor’s peak current to about 4.4 A by default, as well as built-in undervoltage, overcurrent, and overtemperature protection. The carrier board additionally provides reverse-voltage protection
