This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual TB9051FTG motor drivers operate from 4.5 to 28 V and can deliver a continuous 2.6 A per motor (5 A peak). These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. A fixed current chopping threshold allows each TB9051 to limit the peak motor current, and they feature built-in protection against under-voltage, over-current, and over-temperature conditions; our shield also adds reverse-voltage protection. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
