VNH5019 Dual Motor Driver Shield for Arduino This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board (Arduino MCU sold separately). Its dual robust VNH5019 motor drivers operate from 5.5V to 24V and can deliver 12A continuous (30 A peak) per motor, or a continuous 24A (60 A peak) to a single motor connected to both channels. These drivers offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be modified if the defaults are not compatible with your project, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
Wide operating voltage range: 5.5V - 24V High output current: up to 12A continuous (30A maximum) per motor Motor outputs can be combined to deliver up to 24A continuous (60A maximum) to a single motor Inputs compatible with both 5V and 3.3V systems (logic high threshold is 2.1V) 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) Motor indicator LEDs show what the outputs are doing even when no motor is connected Can be used with an Arduino or Arduino clone (through shield headers) or other microcontroller boards (through 0.1" header along the left side) When used as a shield, the motor power supply can optionally be used to power the Arduino base as well Detailed user's guide and Arduino library www.Pololu.com, Product # 2507.
