Pololu Dual VNH5019 Motor Driver Shield for Arduino

This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, high-power brushed DC motors with an Arduino board or a compatible board such as the A-Star 32U4 Prime. The board features two robust VNH5019 motor drivers from ST, which operate at voltages from 5.5 to 24 V and can deliver a continuous current of 12 A (peak current 30 A) per channel.

Features:

• Wide operating voltage range: 5.5 – 24 V1
  
• High output current: up to 12 A continuous (30 A peak) per motor
  
• Motor outputs can be combined to deliver up to 24 A continuous (60 A peak) to a single motor
  
• Inputs compatible with 5V and 3.3V systems (logic high threshold is 2.1 V)
  
• PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
  
• Current sense voltage output proportional to motor current (approx. 140 mV/A; only active while H-bridge is driving the motor)
  
• Motor indicator LEDs show the status of the outputs, even when no motor is connected
  
• Can be used with an Arduino or Arduino clone (via shield headers) or other microcontroller boards (via the 0.1″ header on the left side)
  
• When used as a shield, the motor power supply can optionally also be used to power the Arduino base
  
• The Arduino pin assignments can be customized if the default assignments are not suitable
  
• The Arduino library makes it easy to get started using this board as a motor driver shield
