Pololu Dual VNH5019 Motor Driver Shield for Arduino

Get your Arduino moving! 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.

This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, high-power, brushed DC motors with an Arduino or Arduino clone. The board features a pair of robust VNH5019 motor drivers from ST, which operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per channel, and incorporates most of the components of the typical application diagram on page 14 of the VNH5019 datasheet (1MB pdf), including pull-up and protection resistors and FETs for reverse battery protection. It ships fully populated with its SMD components, including the two VNH5019 ICs, as shown in the picture to the right; stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in (see the Included Hardware section below).

Features:

1. High Output Current: Up to 12 A continuous (30 A maximum) per motor
2. Combined Motor Outputs: Deliver up to 24 A continuous (60 A maximum) to a single motor
3. Logic Compatibility: Inputs compatible with both 5V and 3.3V systems (logic high threshold at 2.1 V)
4. PWM Operation: Supports up to 20 kHz for quieter motor operation
5. Current Sensing: Provides voltage output proportional to motor current (approx. 140 mV/A)
6. Motor Indicator LEDs: Show output status even without a motor connected
7. Versatile Compatibility: Works with Arduino or Arduino clones via shield headers and other microcontrollers via 0.1” header
8. Power Supply Options: Can power the Arduino base when used as a shield
9. Customizable Pin Mappings: Allows for adjustments to Arduino pin configurations
10. Arduino Library Support: Simplifies integration as a motor driver shield.
