VNH5019 Motor Driver Shield for Arduino info

VNH5019 Motor Driver Shield for Arduino makes it easy to control two bidirectional, high-power, brushed DC motors with an Arduino or compatible board. 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. VNH5019 Motor Driver Shield for Arduino has pull-up and protection resistors and FETs for reverse battery protection.

VNH5019 Motor Driver Shield for Arduino is intended for a wide range of users, from beginners who just want a plug-and-play motor control solution for their Arduino boards to experts who want to directly interface with ST’s great motor driver ICs. The Arduino pin mappings can all be customized if the defaults are not convenient, and the VNH5019 control lines are broken out along the left side of the board for general-purpose use without an Arduino. This versatility, along with an option to power the Arduino directly from the shield, sets this board apart from similar competing motor shields.
