Pololu Dual VNH5019 Motor Driver Shield (Arduino Compatible)
Motor outputs can be combined to deliver up to 24 A continuous to a single motor
Ultrasonic PWM operation up to 20 kHz
Current sense voltage output proportional to motor current (only active while H-bridge is driving)
Motor indicator LEDs show what the outputs are doing even when no motor is connected
Arduino or Arduino clone compatible (through shield headers) or other microcontroller boards
This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. 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.
